Occasional 'NoneType' object is not iterable

[burner1024]

Hi!
I'm getting this error occasionally:

Traceback (most recent call last):
  File "/usr/local/lib/python3.9/site-packages/pyaarlo/background.py", line 35, in _run_next
    job["callback"](**job["args"])
  File "/usr/local/lib/python3.9/site-packages/pyaarlo/media.py", line 197, in update
    for video in data:
TypeError: 'NoneType' object is not iterable

My pyaarlo version is a little behind, but from what I see, this code also hasn't been changed for quite some time.
