That message almost always indicates that one or more of the plugins installed on your Jenkins controller have an issue with configuration form modernization that was implemented in Jenkins 2.277.1. See https://community.jenkins.io/t/migrating-jenkins/894/5 for detailed steps that you can take to identify the plugin or plugins that are causing the issue.

I confirmed with my Jenkins controller that Pipeline syntax is generated as expected from the copyartifact plugin when I leave all fields at their default values. I also confirmed that the syntax was generated correctly when I used non-default values.

markewaite Thank you for your reply. I have partially followed the steps from the link you provided, though not in great detail as they get very technical.

It may be significant that we have two Jenkins controllers, with identical plugins, one of which shows the problem, the other does not (snippet generator works as expected). The only significant differences are that the non-working controller is configured with Active Directory and has numerous agents, whilst the working controller has 'Security Realm' set to 'Jenkins own user database' and has no agents. Could those facts be relevant?

With two Jenkins controllers, one working, and one not, it may be most effective to compare the exact list of plugins on the two controllers so that you can see which "extra" plugins are installed on the controller that has the issue but are not installed on the controller that does not have the issue.

Use the Jenkins script console (in "Manage Jenkins") to run the plugin version report script on each controller, then compare the results between the two systems. The problem plugin is likely installed on the system with the issue and not installed on the other system.

If the plugins and versions on the two controllers are truly identical, then it might be that the authentication configuration affects it, though that would surprise me.
