Jenkins Error after upgrade - "Not all environment variables could be successfully injected."
05:30 19 Sep 2022

After the upgrade from Jenkins "1.651.3" to "2.346.3 LTS".

My job log contains this message many times:
ERROR: Not all environment variables could be successfully injected. Check for similarly-named environment variables.

There is no clue. How to find which variables could not be successfully injected?
