Hi Team,

Recently we have upgraded our jenkins from 2.19.3 to 2.164.1.

After that whenever we run any build flow job, the job is completing successfully but jenkins is not able to save it on UI. During next jenkins restart or next day the job is getting removed from build history.

Build flow plugin version is 0.20.

Below are the error logs from jenkins server.
