why no error with a 404 response?

[PierBover]

The openapi-fetch docs mention that there should be an error object with a 404 response:

5xx, 4xx, or default response if not OK; otherwise undefined

I'm running openapi-fetch in Node 22 and getting an empty string instead.

Is this expected behavior?

Figured out.

The docs don't seem to mention this but the error object is not an actual error... but the body response from a non 2xx response.

So obviously this object will be empty if the response doesn't have a body.
