No issue with validation but unable to execute *-wrapper.py

Greetings,

My librenms have issue to show the graph and certain cron jobs not running as well.

I have validated the installation and it seem like no problem but getting python error (I guess) when trying to execute discovery-wrapper.py and poller_wrapper.py. Any suggestions on how to solve this problem?

Your suggestions would be greatly appreciated.

Thanks & regards,
