mcollina · 2026-02-06T13:01:57Z

The CI failures are caused by a bug in undici 7.20.0 where __filename is not defined when undici is bundled inside Node.js as an internal module.

When fetch() fails, the code in index-fetch.js tries to access __filename to augment the stack trace, but this throws a ReferenceError that swallows the original error, making err.cause undefined.

Fix PR: nodejs/undici#4812

mcollina · 2026-02-06T13:12:52Z

This is fixed in undici v7.21.0
