Unexpected KeyError while running test suite inside GitLab Worker

[konstista]

Hello there, I'm looking for help.
Basically all of a sudden started getting unexpected KeyError while running test suite inside GitLab Worker.

It seems like no dependencies were updated, no extra code was recently added. Pipelines seem to fail even for the code that previously passed all tests. Interesting that everything works fine locally.

Error Trace

ImportError while loading conftest '.../tests/conftest.py'.
/usr/local/lib/python3.8/site-packages/ddtrace/internal/module.py:

E   KeyError: 'http://json-schema.org/draft-03/schema'

Error happens when importing validate() from jsonschema.
In all test cases the function is not being called, it fails on import.

Implementation

Implementation is fairly straightforward: try/except block wrapped in a function.

 try:
     validate(entity, schema)
     return True
 except Exception as e:
     return False

The issue seems to be somewhere on my side, but I don't think something changed in the docker executor. The code itself is perfectly functional. Would be very appreciated for any help.

I can overcome the issue with moving import to function local scope. As the function is never called in the test suite - the import never happens. But I'm just curious about the behaviour.

Same issue when running with Github runners. Locally it works without any issue.

There isn't enough info to be helpful I'm afraid. All passes here in CI in GitHub Actions without doing anything special. The error message points to you possibly doing something wrong to break normal installation of static (non-Python) files but hard to say what.

(Going to convert this to a discussion. If there's more info there's a small chance I can help you figure it out but no promises.)
