v2 Error: Expected a string but received a Array

[thangleiter]

Today I experienced the same problem as https://github.com/codecov/codecov-action/issues/561, however, migrating from v1 to v2 did not help me. Instead, I get a new error with the uploader exiting with code 255:

[2021-10-25T17:54:04.067Z] ['verbose'] The error stack is: TypeError: Expected a string but received a Array

Error: Codecov: Failed to properly upload: The process '/home/runner/work/_actions/codecov/codecov-action/v2/dist/codecov' failed with exit code 255

The codecov block in my yaml looks like this:

- name: Upload coverage to Codecov
  uses: codecov/codecov-action@v2
  with:
    file: ./coverage.xml
    name: ${{ matrix.python }} - ${{ matrix.install_extras }}
    env_vars: OS,PYTHON
    fail_ci_if_error: true
    verbose: true

I have this error as well.

      uses: codecov/codecov-action@v2
      with:
        fail_ci_if_error: true
        file: ./coverage.xml
        flags: tests
        name: ${{ matrix.py }} - ${{ matrix.os }}
        verbose: true

Any updates on this? v3 and master also fail while v1 works just fine.

I have the same question when I use it by docker on windows. How to solve it.

I'm going to close this out as there isn't enough information to debug. My best guess is that one of the arguments being passed into name is an array and not a string. If you are still running into the issue, please open a topic in our community boards

I also ran into this issue when using the CircleCI Codecov orb and invoking codecov/upload from a matrixed job. Same stack trace as well when in verbose mode.

I don't think the name is a factor, as the stack trace seems to imply that it failed the validation of the token.

I wonder if this is an issue with the use of matrices and the uploader? @thomasrockhu-codecov
