I am trying to understand what causes it. I can't find an issue with any of my jobs. I listed all job names and I couldn't find any of it to be empty or looking suspicious. 

I set via the UI > log extended logging (ALL) for following loggers:

hudson

net.uaznia.lukanus.hudson.plugins.gitparameter.GitParameterDefinition

java

Then I checked the related log from the UI, but I could not find any additional hints. 

In the log there is nothing related right before and right after the exception, that could point me to the root cause. 

I was able to find only issue "JENKINS-46216">JENKINS-46216" which looks similar to mine, but it doesn't help me to understand my issue. 

Would anyone knows what could be causing this exception or how to further investigate it?

Thanks!
