Level=error msg="Failed to notify(sent: false): <nil>"

I have open an issue on the GitHub, but may be it is preferable to open a discussion here ?
I get messages error logged about in /var/log/crowdsec.log (on my main server)…

level=error msg="Failed to notify(sent: false): <nil>"

This is an error message related to sd_notify , which allows to notify the init process that we are up.
The error can be safely ignored (it might happen if your init system does not support notifications, or if you are starting crowdsec directly).

thanks @blotus for the explanation !
