Troubleshooting

“The Writing Room can’t start in this Studio yet.” The room and the Studio are using different copies of Sanity’s App SDK. On a deployed Studio, turn off auto-updates (Install, step 3) and deploy again. In sanity dev, run npm ls @sanity/sdk-react: it should appear at a single version. If you’ve linked the plugin (npm link, file:, a workspace) instead of installing it, add sanity, react, react-dom, styled-components, @sanity/sdk-react and @portabletext/editor to Vite’s resolve.dedupe in sanity.cli.ts.

Yarn, or two copies of the SDK. npm (7+) and pnpm install the plugin’s peer dependencies for you, and share @sanity/sdk-react and @portabletext/editor with Sanity when your sanity version is in range. Yarn doesn’t install peers: add @sanity/sdk-react@^3.12.0 and @portabletext/editor@^8.2.12 yourself. To check, run npm ls @sanity/sdk-react @portabletext/editor: each should appear at a single version.

A type is missing from the Lobby. Open the browser console: the room says why it left a type out (not in the schema, or no title or body it could find). Name the field with fields if it guessed wrong.
