I am running a Jenkins server based on https://hub.docker.com/r/jenkins/jenkins LTS. While running version 2.332.1, I have noticed the following exceptions during initialization, which I have not seen before.
Any help regarding how to solve this is highly appreciated.

How do I find out what causes this and how to correct it?
CodePudding user response：
I found the reason. The "Pipeline: Nodes and Processes" plugin was not updated because Jenkins said it was incompatible. After updating it the exception is gone, and it seems like the whole system is still running
