Cannot unmarshal object into Go struct field resultSet.coverage

Describe the bug

Hello there, I am not quite sure what I am missing here. I'm running my tests with RSpec inside a container. Can you please help out? I tried many different things already.

    - name: Run tests
      run: docker-compose run --rm -e RAILS_ENV=test web bin/rails spec
      env:
        CC_TEST_REPORTER_ID: ${{ secrets.CC_TEST_REPORTER_ID }}

    - name: Publish code coverage
      uses: paambaati/codeclimate-action@v3.0.0
      env:
        CC_TEST_REPORTER_ID: ${{ secrets.CC_TEST_REPORTER_ID }}
      with:
        debug: true
        coverageLocations: ${{github.workspace}}/coverage/coverage.json:simplecov

The error I am getting:

Version of codeclimate-action you're using v3.0.0 With simplecov gem (0.21.2)

Expected behavior

Send coverage to CodeClimate
