[JENKINS-72132] GitHub Branch Source w/ GitHub App Authentication fails to auth periodically

 

Periodically, a job will fail with this below issue. 

My approximate timing is that it fails once per hour. And then succeeds after that.

 > git --version # 'git version 2.42.0.windows.2'

using GIT_ASKPASS to set credentials ORG Automation Github App. Should give access to pull repos

 > git.exe fetch --no-tags --force --progress – https://github.com/org/repo.git +refs/pull/17/head:refs/remotes/origin/PR-17 # timeout=10

ERROR: Error cloning remote repo 'origin'

The setup for the job is as follows: * Multibranch Pipeline job

• Github branch source


• Github App credential


• Scans repo every 5 minutes.

 

The jobs don't get re-run automatically if they fail due to this. We are in a migration process and are attempting to limit the number of issues and hurdles to ease the transition of a team away from a CVS repo.
