…encies debounce-promise is imported at runtime in MessageProcessor.ts but was declared as a devDependency. It previously resolved only via hoisting, which fails under strict installs such as pnpm v11 and causes graphql-lsp to crash with "Cannot find module 'debounce-promise'". Move it to dependencies and add @types/debounce-promise to devDependencies.

Monaco splits the hovered word on `:`, so a full URL like `https://example.com/img.png` reaches the preview as the protocol-relative `//example.com/img.png`. The preview stripped the leading character, turning that into the host-relative `/example.com/img.png` and fetching it from the current origin. The original host is now preserved. - Updated dependencies [[`a526a10`](a526a10)]: - graphql-language-service@5.5.2 ## graphql-language-service@5.5.2 ### Patch Changes - [#4329](#4329) [`a526a10`](a526a10) Thanks [@vishwakt](https://github.com/vishwakt)! - Make the fields block optional when parsing object, interface, input, and enum type definitions (and their extensions) in the online parser. Per the GraphQL spec these blocks are optional, so spec-valid SDL such as `extend type Foo @onType` or `type Foo @onType` (directives only, no body) no longer reports `invalidchar` during syntax highlighting. ## graphql-language-service-server@2.14.10 ### Patch Changes - [#4328](#4328) [`d6b71ce`](d6b71ce) Thanks [@vishwakt](https://github.com/vishwakt)! - Move `debounce-promise` from `devDependencies` to `dependencies`. It is imported at runtime in `MessageProcessor.ts`, so it must be a regular dependency. Previously the package only resolved it via hoisting, which fails under strict installs (e.g. `pnpm` v11), causing `graphql-lsp` to crash with `Cannot find module 'debounce-promise'`. - [#4331](#4331) [`e1077b9`](e1077b9) Thanks [@vishwakt](https://github.com/vishwakt)! - Import `Logger` from `vscode-jsonrpc` instead of `vscode-languageserver`. `Logger` is defined in `vscode-jsonrpc` (a direct dependency) and only reached `vscode-languageserver` through a transitive re-export, which `tsgo` failed to resolve on CI (`Module '"vscode-languageserver"' has no exported member 'Logger'`). Importing from the package that owns the type avoids relying on that fragile re-export chain. - Updated dependencies [[`a526a10`](a526a10)]: - graphql-language-service@5.5.2 ## vscode-graphql-execution@0.3.6 ### Patch Changes - [#4306](#4306) [`7aefde8`](7aefde8) Thanks [@dependabot](https://github.com/apps/dependabot)! - Bump `ws` to 8.20.1 to address [GHSA-58qx-3vcg-4xpx](GHSA-58qx-3vcg-4xpx) (uninitialized memory disclosure in `websocket.close()`).

Summary
graphql-language-service-serverimportsdebounce-promiseat runtime inMessageProcessor.ts, but it was declared as adevDependency. It previously resolved only through dependency hoisting (the siblinggraphql-language-servicepackage lists it as a real dependency), which breaks under strict, isolated installs such aspnpmv11. There,graphql-lspcrashes on startup withCannot find module 'debounce-promise'.This moves
debounce-promiseintodependenciesso it is always available at runtime, and adds@types/debounce-promisetodevDependenciesso type-checking no longer relies on hoisting either.Fixes #4324.

debounce-promisewas the only genuinely mis-declared runtime dependency (@graphql-tools/loadis a type-only import and is erased at build time).tsgo --buildandtsgo --noEmitongraphql-language-service-serverpass; thedebounce-promiseimport and its types resolve correctly.Credit
Thanks to @dylanarmstrong for the report and for correctly diagnosing the root cause in the issue.
