Hi All,

Wonder if anyone can help me, i keep getting an error back from the bridge

[Bridge] Error: Unexpected error: 'utf-8' codec can't decode bytes in position 8034-8035: invalid continuation byte

So date is fed into the LM studio and the data that comes back then generates the above error.. i think this does not feed back into the AI in factorio, and i am assuming this is in python that is generating the error

Can anyone help or tell me where to look to find out more details on this

Better trace of error
