Bug Description

DingTalk adapter has multiple bugs preventing message processing. Messages are received but never processed, causing timeout errors and infinite reconnection loops.

Symptoms

• Gateway logs show TimeoutError in process() method
• Error: object tuple can't be used in 'await' expression
• Infinite reconnection loops
• Messages never reach the agent
• Gateway appears connected but doesn't respond to any DingTalk messages

Root Cause

The DingTalk adapter (gateway/platforms/dingtalk.py) has 6 bugs that were identified and fixed in PR #5038, but that PR has not been merged yet:

1. DingTalkStreamClient.start() is async but was wrapped in asyncio.to_thread(), which is for sync functions only. The coroutine was never awaited, causing infinite reconnection loops.

2. ChatbotHandler.process() is async in the dingtalk-stream SDK, but the adapter defined it as a regular function. The SDK tried to await the returned tuple, causing "object tuple can not be used in await expression".

3. process() blocked with future.result(timeout=60) — agent responses take longer than 60s (LLM inference, tool calls), causing TimeoutError and preventing timely ACK.

4. _extract_text() reads wrong field — uses getattr(message, "text") which returns None on CallbackMessage. The SDK stores text in message.data["text"]["content"]. Messages were silently dropped as empty.

5. _on_message() uses getattr() for all fields (conversation_id, sender_id, session_webhook, etc.) but CallbackMessage stores everything in message.data with camelCase keys. All fields resolved to defaults — session_webhook was never captured, replies impossible.

6. Authorization uses encrypted senderId ($:LWCP_v1:$...) instead of readable senderStaffId (numeric corp employee ID), making allowlists impractical.

Temporary Fix Applied

I applied the fixes from PR #5038 locally, and DingTalk integration now works perfectly:

# 1. Direct await on stream_client.start()
await self._stream_client.start()

# 2. async def process() with fire-and-forget task dispatch
async def process(self, message):
    future = asyncio.run_coroutine_threadsafe(self._adapter._on_message(message), loop)
    future.add_done_callback(_log_error)
    return dingtalk_stream.AckMessage.STATUS_OK, "OK"

# 3. _get_field() helper with camelCase key mapping for CallbackMessage
_DATA_KEY_MAP = {
    "message_id": "msgId",
    "conversation_id": "conversationId",
    "conversation_type": "conversationType",
    "sender_id": "senderId",
    "sender_nick": "senderNick",
    "sender_staff_id": "senderStaffId",
    "conversation_title": "conversationTitle",
    "create_at": "createAt",
    "session_webhook": "sessionWebhook",
}

# 4. Use senderStaffId as primary user_id for authorization
auth_user_id = sender_staff_id or sender_id

Request

Please merge PR #5038 as soon as possible. The DingTalk adapter is currently broken in v0.8.0, and many Chinese users rely on DingTalk for enterprise AI assistant deployments.

Environment

• Hermes Agent: v0.8.0 (2026.4.8)
• Python: 3.11.15
• dingtalk-stream: 0.24.3
• Platform: Linux (Alibaba Cloud)
• Location: Xi'an, China

Impact

This bug completely blocks DingTalk integration for all Chinese enterprise users. DingTalk is the most popular enterprise communication platform in China (equivalent to Slack + Teams), and this bug makes Hermes unusable for Chinese deployments.
