PyCharm + Pytest + pytest-cov = Viewer always shows 0%

I'm contributing to an open source project that relies on pytest + pytest-cov. My interpreter is configured as a Docker (not compose) based Python interpreter from an existing image (built manually).

I'm able to run tests OK, both on a standalone shell, as well as with the run configuration below:

And I get this output:

/usr/local/bin/python3 -m pytest --cov=homeassistant.components.digital_ocean --cov-report=xml --cov-report=term-missing --cov-branch ./tests/components/digital_ocean/

As you can see, Coverage is being captured and assessed, but then I load this file into PyCharm, I only see 0%:

What I am doing wrong?

EDIT:

I've also tried using the bundled coverage.py and using PyCharm's “Run with Coverage” feature, but it achieves the same results. For this I've added the `--no-cov` modifier to pytest:

/usr/local/bin/python3 /opt/.pycharm_helpers/coverage_runner/run_coverage.py run --branch --omit="/Users/peixoto/Library/Application Support/JetBrains/Toolbox/apps/PyCharm-P/ch-0/232.10227.11/PyCharm.app/Contents/plugins/python/helpers*" -m pytest --no-cov --cov=homeassistant.components.digital_ocean --cov-report=xml --cov-report=term-missing --cov-branch ./tests/components/digital_ocean/
