v2.0.25 fails with 404 when using {repository} URL parameter set to ${{ github.repository }}

[Tom Hayward]

We have a workflow that requests the list of files modified by a PR. Here's the code:

name: kube-score
on:
  # pull_request workflows run in the context of the fork, when applicable, and
  # thus does not have permission to comment on the PR. To support this, this
  # workflow only publishes an artifact and the comment will be posted by the
  # pr-comment workflow.
  # https://github.blog/2020-08-03-github-actions-improvements-for-fork-and-pull-request-workflows/#improvements-for-public-repository-forks
  pull_request:
    paths:
      - "**-version.txt"
jobs:
  kube-score:
    runs-on: ubuntu-latest
    timeout-minutes: 10
    steps:
      - uses: octokit/request-action@v2.x
        id: list_files
        with:
          route: GET /repos/:repository/pulls/:number/files
          repository: ${{ github.repository }}
          number: ${{ github.event.pull_request.number }}
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

This stopped working when v2.0.25 was released. The error is not found:

I looked at the diff and it's not obvious why it broke. I switched to - uses: octokit/request-action@v2.0.24 and it started working again.

Is this on a private repository? We do send requests using env.GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} in our tests, and they all passed. I'm not sure what broke either.

Can you please create a secret ACTIONS_STEP_DEBUG and set it to 1? That will enable debug logs

@gr2m I experienced a similar issue with a 'Not Found' error. For me, it looks like the repository parameter is not registering. I tested it out and if I have a setup like:

      - name: GET REPO
        uses: octokit/request-action@v2.x
        id: getRepo
        with:
          route: GET /repos/{repo}
          repo: ${{github.repository}}
          mediaType: '{"Accept": application/vnd.github.v3+json}'
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

I get the error, but if I replace the route to look like this without the repo parameter:

 route: GET /repos/${{github.repository}}

It works

[Gregor Martynus]

It might be related to URL parameter encoding, see my comment here: #69 (comment)

Can you try setting owner / repo separately? The / character in github.repository is what is likely causing the problem here

[Tom Hayward]

Yes, that was it. Following 9736caa works. The workflow had not been updated with that usage change.

I'd recommend bumping more than just the patch version to indicate there was a breaking change.

I'd recommend bumping more than just the patch version to indicate there was a breaking change.

That change was not intentional, I'll try to fix/workaround it and push another version today

[Tom Hayward]

Thanks for clarifying the title!

In case you're still curious, here's the debug log: https://gist.github.com/kd7lxl/29ad1c2144692e49cc7067e2af634a87

[Gregor Martynus]

Thanks! You can see the incorrect URL encoding of the repository owner/name in https://gist.github.com/kd7lxl/29ad1c2144692e49cc7067e2af634a87#file-action-log-L102, that's why you get a 404
