# explicitly configure permissions, in case your GITHUB_TOKEN workflow permissions are set to read-only in repository settings
permissions:
  actions: write
  contents: write
  pull-requests: write
  statuses: write

Does it work?

[nlordell]

It didn't work no, I kept the PR open as this adds the permissions that are recommended by the CLA bot documentation (see PR description), but maybe it's not needed after all.

Feel free to close if you don't think that it should be merged.
