The json creation was using "matrix_key" as a string literal instead of referencing the matrix_key variable that gets set from the input. This PR fixes the issue.

Before this action on v0.4.0 would write the following json:

{"matrix_key":{"url":"https://frontend-auth.url.com/","paths":"Application:\n","fd_name":"frontend-auth"}}

With this PR it writes the following, which matches the behavior of v0.3.1:

{"frontend-auth":{"url":"https://frontend-auth.url.com/","paths":"Application:\n","fd_name":"frontend-auth"}}

This was tested on a private repository so I can't share the full build, but hopefully the above is enough information.

We should probably update the release notes of v0.4.0 to indicate that it is a broken version and is not compatible with the github-action-matrix-outputs-read action.

Hey all, I am attempting to use the github-action-matrix-outputs-write github action and facing an unexpected error that I'm hoping I can get some assistance with. Here is the usage of the action:

    - uses: cloudposse/github-action-matrix-outputs-write@0.3.1
      if: ${{ inputs.monorepo == 'true' }}
      id: out
      with:
        matrix-step-name: ${{ github.job }}
        matrix-key: ${{ env.APPLICATION_NAME }}
        outputs: |-
          comment: ${{ env.URL }}

This is the error I'm getting

Error: bad file '-': yaml: mapping values are not allowed in this context

Here's some more output:

  echo "result=${JSON}" >> $GITHUB_OUTPUT
