DCO fails on PRs with more than 250 commits

[AndreiCostinescu]

The error message is:

The DCO check could not be evaluated because the complete pull request commit list could not be retrieved.

GitHub returned 250 commits from the REST API, so the app attempted to retrieve the full list through GraphQL before evaluating the pull request. That fallback did not complete, so the DCO verdict is unknown.

HTTP status: unknown
GitHub request ID: unavailable

Please retry by re-running the check or pushing a new commit.

I’ve been retrying for quite some time without any change: the dco check fails after 3 or 4 seconds…
