          Has anybody identified a workaround for this issue? Downgrading the plugin didn't seem to work.

          I'm also hitting this. It's preventing any builds of my pipeline job.

          I suspect this is related to

          So to work around the issue I had to manually downgrade branch-api to 2.0.7 by uploading http://updates.jenkins-ci.org/download/plugins/branch-api/2.0.7/branch-api.hpi, and then downgrade cloudbees-folder to 5.18.

          I tried the above mentioned solutions but they alone did not work. I rebased with the latest github branch source and included this fix: https://github.com/shraykay/github-branch-source-plugin/commit/c74981372b02f5c887f2a2bccba952f4cee09d66 and was able to ensure jenkins was working.

          Issue is caused by pull requests/branches opened by people who have left private repositories.
