Periodicaly produce a TypeError: object of type 'NoneType' has no len()

[frimigit]

I use the module with some add_abbreviation() and one add_hotkey() in a keyboard.wait() loop and receive sometime an error while it runs:

Traceback (most recent call last):
File "local-packages\Python311\site-packages\keyboard_generic.py", line 22, in invoke_handlers
if handler(event):
^^^^^^^^^^^^^^
File "local-packages\Python311\site-packages\keyboard_init_.py", line 1110, in handler
elif len(name) > 1:
^^^^^^^^^
