Hi

Im not sure if this is an issue you can help me with but i have failed to find a solution elsewhere. I have used your wrapper to create a bot that successfully runs on my mac. However when I tried to run the bot on a Linux system (raspberry pi) i cannot run the script due to this error. Would you happened to know why i am getting this error?
