App preview shows “Unmatched Route” or 404 screen

Your generated Expo app is missing a route file for the screen you opened.

  1. Note the path shown in the preview error (e.g. /settings).
  2. Ask the chat: “Add the missing screen for /settings and wire navigation to it.”
  3. Or add app/settings.tsx (or the matching route) in the Code editor.

See Preview & workbench.

Published web app or demo URL returns 404

  1. Confirm the project preview builds without errors in the workbench.
  2. Run Web deploy again from the publish flow — old URLs may point to a removed build.
  3. Check Visibility & live demo — private projects on Free may not serve a public demo.

See Account & publishing.

V2 Cloud or API request returns 404

CauseFix
Wrong collection or bucket nameUse col('logical_name') helpers — ask the AI to sync names with the schema
Hook or server function path typoCheck Logs and fix the route in chat
Record deleted or wrong IDVerify the ID in your query matches an existing row

See V2 Cloud & backend.
