Action broken

The action seems broken. I use the following github actions with the workflow yaml:

name: Upload coverage to Codecov
      uses: codecov/codecov-action@v2
      with:
        files: ./coverage.xml
        verbose: true

with the default configuration (didn’t specify a codecov.yml file). When trying to upload the report I in my CI run i get:

 Codecov report uploader 0.1.0

It seems to have started happening today.

Problem seems to have been resolved. Do we know the root cause?
