My checkout repo will failed when branch indexing event trigger the Pull Request CI, and succeed when pull request event triggerr the Pull Request. that is very strange, how can I configure to make the Pull Request triggerred just by pull request.

The details info can be found from [[JENKINS-69178] multiBranch pipeline failed with PR code checkout by GitScm - Jenkins Jira](https://issues.jenkins.io/browse/JENKINS-69178)

if anyone kow the reason and please kindly share with me, thanks & regards.
