Unable to start the bot from IntelMQ-Manager

[kodebrain]

I'm able to run the bot from the terminal by running intelmqctl run CERTBundKontakt-Expert but can't start from the IntelMQ-Manager. Issue is only with the CERTBund bots and every other bots can be started/stopped from the GUI.

Checking the logs from the IntelMQ Monitor tab
Logs > Log Level: All doesn't display anything but when I filter it down to Info it list some logs. It should list every type of logs when All is selected ?

What does intelmqctl start CERTBundKontakt-Expert show? That starts the bot as a daemon and is the same command that the Manager (actually the IntelMQ API == the backend) executes.

I suspect that the executable (/usr/(local/)bin/intelmq.bots.experts.certbund_contact.expert) is missing.

I can stop the bot from the Manager after it runs as above but can't start it

This is interesting. Another possible reason could be, that executables of these bots are not in $PATH.
What do which intelmq.bots.experts.deduplicator.expert and which intelmq.bots.experts.certbund_contact.expert show?
