No entry point in ${appDir}: expected one of ${candidates.jo

Error message

No entry point in ${appDir}: expected one of ${candidates.join(", ")}

What it means

Thrown by entryPointFor in the bundle command when no expected raw-app entry file exists in the app directory. The candidate list is framework-aware (detectFrameworks decides it): ['index.ts','index.tsx','index.js'] when Svelte or Vue is detected, ['index.tsx','index.ts','index.js'] otherwise. The error names every candidate tried, so the directory was checked and none of them present — the raw app is missing its entry file or you pointed the command at the wrong directory.

Solutions

1. Create one of the listed candidate files in the app dir — for Svelte/Vue apps index.ts, otherwise index.tsx is conventional
2. Rename an existing differently-named entry (e.g. main.tsx, App.tsx) to the expected index.* name
3. Verify the directory passed to the bundle command is actually the raw app root
