Error message

errors[0].message + '\n' + errors[0].details

What it means

After running the rspack bundling path, internalBundle inspects the compilation output's errors array. If there is at least one error, it throws the first error's message concatenated with its details. This is a pass-through of the underlying rspack build error (module not found, syntax error, resolve failure, etc.), not a Remotion-specific fault.

Solutions

1. Read the full message + details to identify the failing module and the underlying cause.
2. Fix the offending import/syntax/missing dependency, then re-run.
3. Confirm all packages in the user project are installed (bun install / npm install).
4. If the error references an internal Remotion module, check that Remotion packages are at compatible versions.

Example fix

// before
// import {Sequence} from 'remotion-extra'; // package not installed -> rspack error

// after
import {Sequence} from 'remotion';

try {
  await bundle({entryPoint, bundler: 'rspack'});
} catch (err) {
  const msg = String((err as Error)?.message ?? '');
  if (msg.includes('Module not found') || msg.includes('resolve')) {
    // surface the specific module/import path to fix
  }
  throw err;
}

When it happens

Trigger: Any rspack compilation error during bundling: unresolved import, syntax/parse error, circular/missing module, loader failure. The thrown message is rspack's own first error.

Common situations: Missing or misinstalled dependency; typo in an import path; TypeScript/JSX syntax error in user code; incompatible loader/version; missing file extension that resolve rules can't recover.
