🐛 fix(model-runtime): enrich stream parse errors with provider/model context#14636
Conversation
… context
When the OpenAI / Anthropic SDK iterator throws (most often a JSON
SyntaxError on a malformed SSE chunk — e.g. an upstream response with an
illegal backslash escape), `convertIterableToStream` previously only
surfaced `message`/`name`/`stack`. Downstream error logs (agent-gateway
errors table) end up with just "Bad escaped character in JSON at
position 160050" and no way to correlate which provider/model produced
it or whether the same offset keeps recurring.
This change threads optional `{ provider, model }` context through
`convertIterableToStream` / `readableFromAsyncIterable` and enriches the
FIRST_CHUNK_ERROR payload with:
- `provider` / `model` so triage can group identical upstream failures
- `parsePosition` extracted from V8 JSON SyntaxError messages
- `causeName` / `causeMessage` when `error.cause` is set (many wrapped
errors carry the actionable detail in `cause` and the bare triplet
drops it)
Threaded through OpenAI/Responses/Anthropic stream handlers, which all
already receive `payload` containing provider/model.

…payload Two review findings on #14636: 1. Wrapped SyntaxErrors lost their parsePosition. Provider SDKs commonly rethrow `JSON.parse` failures wrapped in their own error class (e.g. `APIError(cause: SyntaxError)`), so the outer `error.name` is no longer `'SyntaxError'` and the previous check skipped extraction for the exact case this enrichment was meant to diagnose. Now `extractParsePosition` walks both the outer error and any `Error` cause, and accepts any error whose message still carries the `"JSON at position N"` signature even if the SyntaxError name was lost in wrapping. 2. Cause cloning could blow up the entire diagnostic path. `structuredClone` succeeds on values that `JSON.stringify` later throws on (BigInt, circular refs), so a non-Error cause carrying either would surface as `payload.cause = clonedObject`, then the outer `JSON.stringify(payload)` would throw inside the catch handler, and the FIRST_CHUNK_ERROR chunk never gets emitted. Replaced with `safeJsonStringify` (BigInt → string, cycles → `[Circular]`) and route the cause object through `toJsonSafe` so the returned shape is always plain JSON. Added tests for both: a wrapped APIError(cause: SyntaxError) yields parsePosition, and a cause containing both BigInt and a circular ref still emits a parseable error chunk.

# 🚀 LobeHub Release (20260518) **Release Date:** May 18, 2026 **Since v2.1.58:** 208 merged PRs · 209 commits · 16 contributors > v2.2.0 introduces the **Chief Agent Operator** — an agent that runs itself end-to-end. It self-iterates against its own output, assembles sub-agent teams on demand through the heterogeneous runtime, and drives a unified task system that knows when to pause for a human. Self-review, AssistantGroup, and tasks/scheduling all converge into one operator surface. --- ## ✨ Highlights ### 🎩 Chief Agent Operator - **Self-iteration exits Lab** — Agent Signal's self-review pipeline ships proposal actions straight into briefs and auto-executes the approved follow-ups, with prompts hardened against eval. The operator now critiques and re-runs its own work without a human in the loop. (#14769, #14583, #14647, #14882) - **Auto-formed agent teams** — Heterogeneous AssistantGroup gains Monitor-style signal callbacks, read-only SubAgent threads with breadcrumb headers, and a thread switcher. The operator dispatches sub-agents and you can step into any branch to see what the team is doing. (#14859, #14658, #14845, #14715) - **Task system as the operator's runway** — Claude Code surfaces task tools, AskUserQuestion freeform notes, and a dedicated `waitingForHuman` topic status; `lobe-task` exposes `setTaskSchedule`; the scheduler is hardened (maxExecutions cap, sub-10min heartbeat block, race-free SchedulerForm). Long-running operator runs no longer go silent and stop themselves when human input is needed. (#14870, #14639, #14713, #14865, #14853) ### 🚀 Cloud & runtime - **Cloud Claude Code V3** — Repo picker, GitHub token flow, and sandbox-aware context bring cloud-hosted Claude Code to feature parity with local; cloud sandbox completion now triggers the task lifecycle end-to-end. (#14568, #14822, #14681) - **Heterogeneous agent multi-replica safety** — Subagent threads, ingest refresh, and parallel-tool counts now survive replica swaps without losing parent_id or rolling back tool state. (#14897, #14631, #14806, #14838) - **Built-in tool lifecycle hooks** — `onBeforeCall` / `onAfterCall` land on the built-in tool runtime; sub-agent dispatch moves to `lobe-agent`; self-iteration aligns with the shared inspector pattern. (#14719, #14715, #14827) - **Knowledge base RAG unified** — Client and server share one `KnowledgeBaseSearchService`; KB files preserved on `NoSuchKey` instead of silently lost. (#14673, #14501) ### 💬 Workspace experience - **Home daily brief + recommendations** — The home screen opens with a linkable welcome, paired input hint, and a recommendations module sourced from the operator's hetero action library. (#14589, #14645, #14770) - **Chat mode + redesigned action bar** — The chat input gains a Chat/Agent mode toggle and a re-pitched action bar with icon-and-color action tag chips. (#14774, #14903, #14846) - **Documents tree, optimistic** — Document tree creates, deletes, and inline renames now apply optimistically; the agent-documents index hides web crawls and switches to a table layout. (#14714, #14292) - **Branded MCP inspectors** — Linear MCP tool calls render with the same branded inspector as the built-in Linear skill; CC MCP and built-in skills now share inspector code. (#14864, #14884) - **Bot identity gating** — Device tools are gated by sender identity, the activator bypass is closed, and Slack mpim plus Discord DM regressions are fixed. (#14634, #14664, #14733) --- ## 🏗️ Core Agent & Signal Pipeline ### Self-iteration & Agent Signal - Self-iteration graduates out of Lab, with service, tool, name, and concept structure unified across `agent-signal`, `prompts`, `database`, and `builtin-tool-self-iteration`. (#14699, #14769) - Self-review now proposes actions to briefs and auto-executes the approved set, with eval-verified prompt hardening. (#14583, #14657, #14647) - Self-iteration built-in tool aligns with the shared runtime + inspector patterns. (#14827) - Agent Signal prompts adapt their response language and avoid blocking agent execution. (#14890, #14775, #14882) - Receipt descriptions now carry an Agent Signal marker, and self-review hinted skill documents route correctly. (#14764, #14895) ### Heterogeneous agent runtime - Subagent threads render read-only with a breadcrumb header and thread switcher; SUBAGENT badge dropped, indentation tightened. (#14658, #14845, #14783) - Multi-replica safety: ingest refresh restores tools/model from DB to fix parent_id breaks; new-step assistants sync across replicas; subagent-tagged events no longer leak into the main gateway handler. (#14897, #14631, #14838) - Fetch-triggering events are deferred to keep parallel tool counts from rolling back. (#14806) - AskUserQuestion is wired for Claude Code, with auto-decline disabled and a freeform note input on the cloud side; `waitingForHuman` is a first-class topic status. (#14639, #14629, #14870) - AssistantGroup gains Monitor-style signal callbacks; project skills surface in the working sidebar and markdown preview. (#14859, #14896) - Cloud Claude Code V3 — repo picker, GitHub token, sandbox context; credentials alert and disabled input when not configured. (#14568, #14822) - Cloud sandbox completion now triggers the task lifecycle end-to-end. (#14681) ### Agent runtime & context engine - Built-in tool runtime gets `onBeforeCall` / `onAfterCall` lifecycle hooks. (#14719) - `CompletionLifecycle`, `HumanInterventionHandler`, and `stepPresentation` are extracted from the runtime monolith. (#14441) - Per-tool timeout is honored end-to-end for client tool dispatch. (#14817) - Compression budget accounts for `tool_calls`, reasoning content, and tool defs; `call_llm` forwards tools into the budget. (#14813, #14837) - Pre-flight context check now fails fast for OpenAI-compatible providers. (#14824) - Malformed `tool_call` names are recovered instead of finishing the step silently. (#14577) - Sub-agent dispatch moves from `lobe-gtd` to `lobe-agent`. (#14715) - Hidden built-in tools now appear in the system prompt @-mention list. (#14823) ### Agent tracing & operations - New `agent_operations` table and runtime persistence for every hetero-agent operation. (#14416, #14736) - `signOperationJwt` issues 4-hour signed operation tokens. (#14586) - S3 trace snapshots are zstd-compressed; DB `trace_s3_key` aligns with the `.json.zst` suffix; legacy `.json` fallback preserved on fetch. (#14807, #14860, #14826) --- ## 📱 Platform & Integrations ### Bot / Channels - Device tools are gated by sender identity. (#14634) - Activator bypass closed and device-access checks converged. (#14664) - Slack mpim supported; Discord DM regression fixed; Slack connect + slash commands repaired. (#14733, #14591) - Bot channels, bot watch, bot callback service, and system bot reliability fixes. (#14847, #14796, #14570, #14784, #14649) - Online Messager scaffolding. (#14755) ### Onboarding - Home daily brief with linkable welcome and paired input hint. (#14589) - Recommendations module sourced from the hetero agent action library. (#14645) - Chat onboarding passes request triggers via metadata and preserves the resume request. (#14770, #14798) - Discovery turn progress gated by phase, with a reminder on stalled discovery. (#14842, #14833) - FullNameStep back button rejoins the shared prefix; ModeSwitch hidden in production. (#14898, #14760) - Agent marketplace folds into the web onboarding tool. (#14578, #14672) - Onboarding interests stored as keys instead of free text; early-exit skips marketplace and drops CJK prompts. (#14624, #14598) ### Model providers - Gemini 3.1 Flash-Lite cards; Gemini schema sanitizer drops non-compliant `enum` / `required`; zero `cachedContentTokenCount` handled in usage conversion. (#14604, #14740, #14567) - DeepSeek-V4 model cards and pricing restored to official rates. (#14110, #14911) - ernie-5.1 and spark-x2-flash support; Grok 4.3 `reasoning_effort` support. (#14643, #14731, #14642) - SiliconCloud catalog synced with API; duplicates removed; reasoning params adjusted. (#14464) - Minimax derives `max_tokens` from context window to avoid `ExceededContextWindow`. (#14814) - aihubmix uses the full models endpoint for a complete list; stale empty-apiKey test dropped. (#14511, #14669) - Stream parse errors are enriched with provider + model context. (#14636) - Visual content parts are consumed in the server runtime; video image references move to a JSON object. (#14637, #14900) - Google function call magic `thoughtSignature` now attaches to every part, not just the last turn. (#14904) - Service model assignments settings added; model extend-param options removed. (#14712, #14607) ### Built-in tools & knowledge base - `lobe-task` exposes `setTaskSchedule`; task scheduler hardened (maxExecutions cap, sub-10min heartbeat blocked, SchedulerForm race fix, rapid automation-mode toggle stabilized). (#14713, #14865, #14853, #14801) - KnowledgeBaseSearchService shares RAG runtime across client and server. (#14673) - KB files preserved on `NoSuchKey` and orphan documents/tasks cleaned.

(#14292) - `lobe-clarify` and SKILL.md frontmatter parsing/edit validation are unified. (#14566) - AnalyzeVisualMedia inspector + Portal HTML preview refactor; HTML preview restored for AssistantGroup messages. (#14777, #14811) - Branded inspector shared between CC MCP and built-in Linear skill. (#14884, #14864) --- ## 🖥️ CLI & User Experience ### Chat & Conversation - Chat mode toggle and redesigned chat input action bar. (#14774) - Action tag chips switch to icon + colored label; ActionDropdown closes on sibling-open and focus-out; submenu uses native header/footer slots. (#14903, #14802, #14901) - Action bar padding equalized around the send button; skeleton shows in action bar while config loads.

Surfaced from agent-gateway error triage: an

🔀 Description of Change
When the OpenAI / Anthropic SDK iterator throws (most often a
JSON.parseSyntaxErroron a malformed SSE chunk — e.g. an upstream response containing an illegal backslash escape),convertIterableToStreamincore/streams/protocol.tspreviously only forwardedmessage/name/stackinto theFIRST_CHUNK_ERRORpayload. Downstream consumers (agent-gateway error log, in-app error renderer, Sentry, etc.) end up with a genericSyntaxErrorand no way to:error.causethat wrapped errors (e.g.APIError(cause: SyntaxError)) routinely carryThis PR threads optional
{ provider, model }context throughconvertIterableToStream/readableFromAsyncIterableand enriches the error payload with:provider/model— frompayloadalready present in every stream handlerparsePosition— extracted from V8 JSON SyntaxError messages (/position\s+(\d+)/)causeName/causeMessage— whenerror.causeis anErrorcause— for non-Error causes, deep-cloned viastructuredClonewithString(cause)fallbackThreaded into
OpenAIStream,OpenAIResponsesStream, andAnthropicStream. Other callers (qwen.ts,spark.ts,ollama,huggingface,zhipu) keep working withcontext = undefined— kept out of scope to keep the surface area small; can be wired up later if useful.🧪 How to Test
cd packages/model-runtime bun run vitest run src/core/streams/protocol.test.tsThree new tests covering: provider/model enrichment, JSON
parsePositionextraction, anderror.causesurfacing. All 39 tests pass.📝 Additional Information
Backwards compatibility:
contextis optional everywhere. Existing fields (message/name/stack) are unchanged. The existing test assertingchunks[1].message === 'rate limit'still passes unmodified.What this does NOT fix: the raw upstream SSE chunk that failed JSON.parse is still discarded by the OpenAI SDK (it
console.errorssse.dataand rethrows the bare SyntaxError). Capturing the raw bytes would require teeing the fetch response body before handing it to the SDK — out of scope for this PR. The enrichment here gets us 80% of the diagnostic value (provider/model/position) without that restructuring.🤖 Generated with Claude Code
