Unexpected error in lgpio.py?

Support

Hi, I’m a newbie in the Trilobot territory. When I try to run the flash_underlight.py example, the script loops 10 times as it should. But after Done is printed, I get these strange error messages:

Done
Exception ignored in: <function PWM.del at 0x76662898>
Traceback (most recent call last):
File “/usr/lib/python3/dist-packages/RPi/GPIO/init.py”, line 179, in del
File “/usr/lib/python3/dist-packages/RPi/GPIO/init.py”, line 202, in stop
File “/usr/lib/python3/dist-packages/lgpio.py”, line 1084, in tx_pwm
TypeError: unsupported operand type(s) for &: ‘NoneType’ and ‘int’

8 times.

Can anybody help me understand what’s going on?

Since nobody has answered my question, I myself am writing this comment: it is a problem with Bookworm. With Bullseye the scripts run smoothly.

Sometimes the Latest & Greatest, isn’t always the Greatest. ;)
I run Bullseye on my Grow Hat Mini setups because of similar issues to what you posted. It’s not a big deal now that I know what OS will work with that hardware / software. It did have me scratching my chin for a bit though. :)
