My job shows an Oops error message during a move/copy/promote operation with a null pointer error
The error screen looks like this: image::common-kb::OppsScreen.png[OppsScreen]
CloudBees Jenkins Enterprise
CloudBees Jenkins Operations Center
Migrated Job from and older version/different version of Jenkins
Go to the job you are trying to move: image::common-kb::JobScreenshot.png[JobScreenshot]
hit configure: image::common-kb::ConfigureScreen.png[ConfigureScreen] then save that configuration.
The null pointer is probably from Tag that the Jenkins instance does not understand inside of its config.xml. The save will regenerate the config.xml file and fix the tag which is bad or missing.
