Hi @Heclim, welcome to the Forums!

This is usually a docker configuration issue.  
I don't use docker, but this error means what it says.

The driver cannot access or see the serial port.

ensure its been exposed in your docker configuration correctly and that correct permission have been set. I don't use docker, but I'm sure plenty of folk around here do.

Also, if using docker, you _may_ get issues with a serial port package we depend on,

Further to that, don't use docker unless you have a good reason. It adds complexity.
