## Problem Three Sentry issues, all `Missing requestHandler or method: <method>`, first seen in v2.27.0: | Method | Page | Events | |---|---|---| | `findDocumentColors` | `/settings/mcp-apis` | 170 | | `resetSchema` | `/settings/mcp-apis` | 22 | | `getCodeFixesAtPosition` | `/object/workflow/…` | 4 | The first two are Monaco **JSON worker** methods, the third a **TypeScript worker** method. All of them bottom out in `monaco-editor/esm/vs/editor/common/services/editorSimpleWorker.js` at `$fmr` — the foreign-module dispatcher — with `_foreignModule` still `null`. ## Root cause Two Monaco copies end up on the page at **different versions**: 1. **ESM `monaco-editor@0.52.2`**, bundled by Vite — what GraphiQL 5 uses. 2. **AMD `monaco-editor@0.55.1` from jsDelivr** — `@monaco-editor/react` → `@monaco-editor/loader@1.7.0`, whose default CDN path is hardcoded to `monaco-editor@0.55.1/min/vs`. Nothing calls `loader.config({ monaco })`, so it goes to the CDN. `setupGraphiqlMonacoWorkers.ts` assigns **`globalThis.MonacoEnvironment`**, a single global both instances read, as a module side effect of the lazily-routed `GraphQLPlayground`. So once the playground has been opened, the 0.55.1 CDN instance stops using its own AMD workers and starts getting Vite-bundled 0.52.2 ones. The two versions don't share a worker protocol: 0.52 routes language-service calls through `$loadForeignModule` + `$fmr`, which 0.55's client never sends. `_foreignModule` stays `null`, and every call rejects. On `/settings/mcp-apis` the consumer is `SettingsMcpSetup.tsx` — `<CodeEditor language="json">` for the MCP config. Monaco fires `resetSchema` on `onWillDisposeModel` / `onDidChangeModelLanguage` and `findDocumentColors` continuously, which is why one bug produces 170 events and 22. There is a second, independent bug in the same file: the `switch` only maps `json` and `graphql`, so `typescript` / `javascript` / `css` / `html` fall through to the bare `EditorWorker`, which carries no language service at all. That's the workflow-page `getCodeFixesAtPosition`, and it would break even with matching versions. Impact is worse than the log noise suggests: after visiting the playground, JSON validation/colors in the MCP config editor and TS intellisense/quick-fixes in the workflow code editor silently stop working for the rest of the session. ## Changes - **`twenty-ui/src/input/CodeEditor/CodeEditor.tsx`** — configure `@monaco-editor/react` with the bundled Monaco (`loader.config({ monaco })`) instead of letting it fetch its own from jsDelivr. The import stays dynamic so Monaco is still only downloaded when an editor actually renders; the component shows its existing `Loader` until the loader is configured. - **`twenty-front/src/modules/app/utils/setupMonacoEnvironment.ts`** (new, replaces `settings/mcp-and-apis/utils/setupGraphiqlMonacoWorkers.ts`) — app-level worker factory mapping every label Monaco can ask for: `json`, `css`/`scss`/`less`, `html`/`handlebars`/`razor`, `typescript`/`javascript`, `graphql`, and the generic editor worker as the fallback. - **`twenty-front/src/index.tsx`** and **`.storybook/preview.tsx`** — set it up once for the app and for stories, rather than as a side effect of one lazy route. Dropping the CDN also means the code editors work in self-hosted and air-gapped deployments, which today silently fall back to a broken editor when jsDelivr is unreachable. ## Verification - `nx build twenty-front` passes; `css.worker`, `html.worker` and `ts.worker` chunks are now emitted alongside the existing `editor`/`json`/`graphql` ones. - Monaco stays lazy — `edcore.main` is not statically imported by the entry chunk and is absent from `index.html`'s modulepreloads. Measured against a baseline build of `main`, the entry chunk goes from 2,598,088 B to 2,599,040 B (**+952 B**). - `oxlint` and `oxfmt --check` clean on all touched files; `tsc --noEmit` clean for `twenty-ui` and reports nothing new for the touched `twenty-front` files. Not verified in a browser — worth a manual pass on the playground → MCP tab → workflow code editor sequence that reproduced the original errors.

twenty-ui
Twenty's open-source React UI component library: components, icons, and design tokens built on a zero-runtime, CSS-variable styling layer.
Installation
npm install twenty-ui
react, react-dom, and monaco-editor are peer dependencies (install them in your app). monaco-editor is only required if you use the code editor components.
Usage
Import the base styles once, pick a theme stylesheet, and wrap your app in ThemeProvider:
import { ThemeProvider } from 'twenty-ui/theme-constants';
import { Button } from 'twenty-ui/input';
import 'twenty-ui/style.css';
import 'twenty-ui/theme-light.css';
export const App = () => (
<ThemeProvider colorScheme="light">
<Button title="Click me" />
</ThemeProvider>
);
Components are available from the root entry point or from a specific subpath for better tree-shaking:
import { Button } from 'twenty-ui';
import { Button } from 'twenty-ui/input';
