UnicodeDecodeError - Githubissues

I'm using the command: sudo mpp-solar -s -d /dev/hidraw0 but I keep getting a failure and I can't figure out why. I've tried it on another pi and it works fine there so there is nothing wrong with the physical cable or the inverter etc, it must be something to do with the setup on my non working pi. The working pi has nothing else installed on it and the non working pi does (not sure if that is related to the issue or not). I've run the command above with the -D flag and this is the output:

It seems to be an issue with a character in the message it is trying to send to the mpp?

Thanks
