TypeError: '<' not supported between instances of 'Mock' and 'int'

hello
I have a C3-400 device.

I can connect to the device, get the serial number and even open and close relays.
I got TypeError: '<' not supported between instances of 'Mock' and 'int'

I have tried with the example code shared

I am also getting the same error. Is there anyone who can have a solution?
