I have a Python program using lgpio.py that runs as it should from the command line but fails when loaded as a service. I get the following error:

     Loaded: loaded (/etc/systemd/system/meye.service; enabled; preset: enabled)
     Active: failed (Result: exit-code) since Sat 2024-05-11 10:36:09 EDT; 18min ago

   Main PID: 1921 (code=exited, status=1/FAILURE)
        CPU: 215ms

The unit file is:

I have no idea why I’m getting the error. Can anyone suggest what the issue might be? Thanks.
