Problem description

For a very long time everything worked as is should. Now when web hook is fired from GitLab and received by Jenkins job is not started. Jenkins log shows exception as in the "Logs & Traces" section. In the GitLab web hook log looks OK. Additional strange thing is that if I post the same POST request using Postman, then Jenkins starts the job without any exception.

No. We've moved Jenkins jobs to the GitLab.
