Hi there,  
I’m running Percona via the percona-server-mongodb:6.0.4 container  
When I give it a config file option via --config /etc/mongod.conf it throws the above error.  
I’m running this on a STIG compliant security hardened Red Hat Enterprise Linux 8.7 in a docker container. I’ve been working on this and perhaps someone who is not as new to mongo/percona as I am would be able to shed some light on this. I’ve pasted the full messages I see in the docker logs.  
I’ve also pasted my config file as it currently stands.

```auto

```auto
ReferenceError: cat is not defined
ReferenceError: cat is not defined

Thanks!

Well, rubber ducking for the win. I commented out further in my config file until I found the offending line. It was the fact that there was no /var/lib/mongo directory. Once I mounted a volume to handle that it worked. The ReferenceError message was just masking the real problem.  
Thanks!
