Validator message for wrong version

[CasperWA]

Testing the validator on Materials Cloud's sample OPTIMADE database yields a bit of a cryptic error:

✖: https://dev-aiida-dev.materialscloud.org/optimade-sample/optimade/v123123 - _get_endpoint - failed with error
        ResponseError: Request to 'v123123' returned HTTP code 404.
        Error(s):
          HTTPException: Not Found (N/A)

I believe this has to do with the return code not being correct? But it's difficult to understand from the message here.

Is that with the maximum verbosity? It should give you more than that...

It is not. It is just running it normally.
But maybe it should be with maximum verbosity for errors, if possible?

This is the error message with maximum verbosity:
I ran this on my local instance instead, hence the changed URL.
