Unable to Save Project

[eric....@gmail.com]

Hi All!  I have a project that I am unable to make changes to.  I can't even make a comment in a field then save it down.  I can't even save it down without a comment.  It throws up a screen saying "Oops!  A problem occurred while processing a request."  Not sure where the physical log is, it's not in /var/log/jenkins/jenkins.log.  So I go to Manage Jenkins/System Log/All Jenkins Logs.  It has a big stack trace for the attempted save, I'll paste it below.  Any idea what my issue is?  Thanks!

Note that the project works fine to perform builds...

That almost always means that one or more of the plugins that are active on your system has not been updated for the configuration form modernization that happened in Jenkins 2.277.1.

You'll need to find and remove the plugins that have not been updated.  A detailed guide is available at https://community.jenkins.io/t/migrating-jenkins/894/5

I've started going through the plugins that have issues and pretty quickly ran into the "conditional buildstep" plugin.  I can't disable this plugin because I use it.  Do you have any suggestions?

Thanks,

Eric

The conditional build step plugin was fixed in 1.4.0 for configuration form modernization.  The most recent release is 1.4.3.

If you haven't updated to latest releases of the plugins, that's certainly the first step.

[eric....@gmail.com]

OK, well I have 1.4.2.  That said, I have 82 updates so I'll do as you say and update everything.  Hopefully this covers it.  Thanks Mark!!!

Thanks so much Mark, that fixed it!!!
