[Ray Core] For the same python test, the results of pytest and bazel are inconsistent

[Moonquakes]

What happened + What you expected to happen

The results of using pytest and bazel to test the same python code are different. Pytest always succeeds, while bazel test always throws the following exception. What may be the cause?

Versions / Dependencies

Ray v2.38.0

Reproduction script

The two test statements are:
python -m pytest -v -s python/ray/tests/test_ray_debugger.py
bazel test --build_tests_only $(./ci/run/bazel_export_options) --config=ci --test_env=CI="1" --test_output=streamed -- //python/ray/tests:test_ray_debugger

The error message of bazel test is:

exec ${PAGER:-/usr/bin/less} "$0" || exit 1
