PRs by GitHub-native dependabot lead to 403

[jdb78]

Recently, 403 errors starting popping up. I believe this is linked to moving to the new GitHub-native Dependabot. PRs that are opened by it create the following output:

Create check runs with commit annotations
  Creating GitHub check with 0 annotations for Flake8…
  Creating GitHub check with 0 annotations for Black…
  Error: Error: Received status code 403
  Error: Error trying to create GitHub check for Flake8: Received status code 403
  Error: Error: Received status code 403

When re-running the action manually, the test passes.

I wonder if something changed in the github actions backend.

Hi there, this is caused by a change by GitHub a few weeks ago. You'll have to adjust your workflows. See dependabot/dependabot-core#3253 (comment) for more information and solutions.
