Hi,

after updating to version 1.90 of GitHub API in our Jenkins, we have a problem when getting info about author of PullRequest for some users. It is blocking our automation of Jenkins builds using Github Pull Request Builder plugin. Interesting thing is that the issue is happening only for some users' Pull Requests. For others everything works fine. We haven't found any suspicious pattern in users' settings.

The error looks as follows:

Unable to handle comment for PR# 266904472, repo: xxx/xxx-xxx
java.lang.NullPointerException

According to report in Jenkins Jira (https://issues.jenkins-ci.org/browse/JENKINS-47848) it seems that downgrade to 1.86 should help, but we need to use 1.90 because of other issues.

Could you look onto it or provide some workaround?

Thank you.
