Error message

Entry point "${entryPoint}" not found. Please ensure the file exists.

What it means

Validation in createBundle before esbuild runs: the resolved entry point (either options.entryPoint or the framework-derived default — index.ts for Svelte/Vue, index.tsx otherwise) does not exist on disk in the app directory. The appDir itself is derived from the entry point's dirname or cwd, so a wrong --entry-point flag or running the bundler from a directory without an index file is the usual cause.

Solutions

1. Create the expected entry file (index.tsx for React-style apps, index.ts for Svelte) in the app directory
2. Pass an explicit --entry-point pointing at the real entry file
3. Run the bundle command from the app's root directory so the default entry resolution finds the file
