Hi there,

I've been trying to find out what's causing this issue, I even upgrade Jenkins version from 1.X to 2.19 and still same behaviour. Probably, some evil plugin caused that issue, but still I don't know which one :(

Current labels view of a particular jenkins agent:

But there are a bunch of labels in the configuration section:

And I can access through the labels url filter: https://jjenkins.com/label/sto-win-dragons02/

Do you have any idea what's causing that issue? It is not a big deal, since those labels are also available in the restriction job setup, but from the User point of view it is a bit painful to know what labels are available easily, since they are not admins though.

Thanks so much

I would start with Simple Theme plugin, or whatever adds the background there.

Also, check the Jenkins log for Jelly errors.

Cool, thanks for the advice, it seems something with some class cast: Caught exception evaluating: it.node.labelCloud

I'll review what plugins might cause that issue.

Thanks again!

Hi there,

I don't really know what's causing this issue though, but only when restarting jenkins then those labels are there, but only the very first time, after XX seconds those labels are gone.
