      Jenkins version: 2.204.6

      Jenkins is running directly

      Its installed manually by unpacking the war file 

      Its behind an nginx proxy

      Using chrome

       

      The issue just appeared when we switched our builds trigger from pollSCM to p4 triggers. The way we do this is that we have setup triggers in p4 which invoke a script, and in that script depending on the path of the changed file we calculate which job needs to run and which branch and we post to our jenkins URL. It works very nicely, but just noticed this NPE appearing in the logs. In case of failed builds we were not getting Failed emails with culprits 

      which prompted a lookup in the logs and we found this:

          This NullPointerException comes from code in Jenkins core that is processing the changeset information from p4-plugin, which is apparently returning an unexpected null value. Unfortunately there is nothing that can be done to resolve this issue from the perspective of the Email Extension plugin. I have reassigned this issue to the p4-plugin component.

          Hi umer_ahmed we could not reproduce it. Could you provide us with the version of the Email Extension plugin version that you are using?

          p4 plugin does not use emailext. It uses mailer-448.v5b_97805e3767
