What did you do?

We are running a custom danger file on PR diff:

bundle exec danger --dangerfile=danger/DangerCheckDiff.rb --danger_id=check_diff --fail-on-errors=true

We have started to see failures on CI within the last month or so when running this for PRs that have more than 300 files diff.

Here's the error log:

GET https://api.github.com/repos/procore/android/pulls/18757: 406 - Sorry, the diff exceeded the maximum number of files (300). Consider using 'List pull requests files' API or locally cloning the repository instead. (Octokit::NotAcceptable)
Error summary:
  resource: PullRequest
  field: diff
  code: too_large // See: https://docs.github.com/rest/pulls/pulls#list-pull-requests-files

What did you expect to happen?
