My CasC Export feature is not working

1 minute readKnowledge base

Issue

  • When I try to use the export CasC feature on some Jobs, the UI does not render any yaml, and the stack trace below is printed in the logs.

  • When navigating under Manage Jenkins → CloudBees Configuration as Code export and update, some Jobs are not exported in the items.yaml.

Environment

Resolution

These issues are generally related to Tier 3 Community plugins which are not compatible with CasC. Some examples of plugins causing this kind of error are:

As soon as you uninstall the problematic Tier 3 Community plugin from your instance, both CasC export features (Item level and general level) will work as expected.
