==================================================== 53 passed, 12 warnings in 218.96s (0:03:38) =====================================================

Even though I didn't make any changes in the forked repository, I am getting 12 warnings.

Start by running make test in the Docker environment and compare the warning output with the issue. Inspect parsers/third_party/usecounters.py, the botocore vendored urllib3 warning, and the jsonschema warning source named in the output. Done means the tests still pass without these deprecation warnings.
