monitoring not working

[Gabriel T]

Hello the monitoring displays following error:

Whitelabel Error Page
This application has no explicit mapping for /error, so you are seeing this as a fallback.

There was an unexpected error (type=Internal Server Error, status=500).
${message}

and here are matching logs:

Hello
The monitoring tab is under development and will be available in future versions.
We plan to disable this menu option and open once monitoring is done and verified by our QA.
