      Description

      _Get fetch failed: 500 for http://jenkins:8080/blue/rest/organizations/jenkins/pipelines/testpipe/scm/content?path=Jenkinsfile&branch=main_

       

      when using BlueOcean Pipeline Editor to Jenkinsfile which exists in gitea repo.

      If I take the same Jenkinsfile and create a new repo from it, then use blueocean to create a new pipeline from that new repo, the editor works. I changed the priority from Major to Minor due to this workaround.

      System log shows:

          strobelight Ken added a comment -

          In looking at the configuration, I see I have a Git source (chosen at initial pipeline creation for the new one to test with), but no Gitea source, so added a Gitea source in order for the webhook to work.

          I could get the issue to occur again if I removed the Git source (the one I used to originally create the pipeline).

          So, I guess both are needed:

          • gitea source to handle webhook
          • git source to be used by blue ocean

          Perhaps this falls under "blue ocean needs to have gitea as a git source to choose from"

          Still, perhaps a better handling of NullPointerException?
