jimmy1998, I was hoping to see a Jenkins stack trace. However, it is now clear that the problem is indeed in blueocean-bitbucket-pipeline and has to be fixed there.
So far, I don't see any such fix in https://github.com/jenkinsci/blueocean-plugin/pulls and I don't know whether anybody is working on it. (PR #2196 will not help; it upgrades the build-time cloudbees-bitbucket-branch-source dependency to 2.9.11, but if you have installed that version, then it is used at run time anyway, even without this PR.)
Until there is a fix, you can perhaps work around the issue by using the older Jenkins user interface instead of Blue Ocean.
around have 120 repositories in Bitbucket, if used other repositories in other project, it works
i am use docker jenkins:lts
i tried docker jenkinsci/blueocean images to show problem, have same issue
