I am trying to introduce codecov-action in our project.. We generate report via coverage package:

coverage run -m unittest --verbose Orange.tests Orange.widgets.tests
coverage combine
coverage report

which produces the report in .coverage file. Before we used Travis and we just uploaded the report with codecov command. With codecov-action I added the following section to one of the workflows:

- name: Upload code coverage
      if: matrix.python == '3.7'
      uses: codecov/codecov-action@v1
      with:
          file: .coverage

It seems that it uploads the report but something is wrong with the report and error message does not tell anything: There was an error processing coverage reports. Here is the link to the error/report: https://codecov.io/github/biolab/orange3/commit/9f5fea156917ba0772a059771092c9480b387c07

I think that the format of the report file is wrong since in the documentation there is the report in XML format, but I also cannot find how to produce the report in the correct format with coverage package.
