Regression in loading file-type under Windows #16179
Description
Is there an existing issue for this?
- I have searched the existing issues
Current behavior
The FileTypeValidator runs into (and catches) an exception when trying to load file-type under Windows. This is because require.resolve("file-type") returns an absolute (Windows) path, which one must not plug into loadEsm (see e.g. nodejs/node#31710).
Minimum reproduction code
https://github.com/schulzjo-tng/file-type-windows-issue-repro
Steps to reproduce
- On Windows, run
npm iandnpm startin the linked repository.
If you do not have a Windows machine, take a look at this CI run:
Run npm start
> [email protected] start
> node index.cjs
node:internal/modules/esm/load:195
throw new ERR_UNSUPPORTED_ESM_URL_SCHEME(parsed, schemes);
^
Error [ERR_UNSUPPORTED_ESM_URL_SCHEME]: Only URLs with a scheme in: file, data, and node are supported by the default ESM loader. On Windows, absolute paths must be valid file:// URLs. Received protocol 'd:'
