Region

SBS targets Australia, however the sbsIE can be used internationally 😜

Provide a description that is worded well enough to be understood

While I was troubleshooting and commenting on an SBS related upstream issue 😉, I switched over to yt-dlp to check how it handles that same SBS URI; I was already on the latest nightly version available at this time; but, my system is 32-bit and thus I'm using (Windows) binary yt-dlp_x86.exe, built on py3.7; I was greeted with what appears to be a Python-related ERROR:

yt-dlp -F "https://www.sbs.com.au/ondemand/watch/2208035907943" =>

Full verbose log will be posted below, inside the template's dedicated field...

To indeed verify the issue is specific to py3.7, I downloaded latest "nightly" file yt-dlp from here and then launched it on py3.8.16 (32-bit):

Provide verbose output that clearly demonstrates the problem

• Run your yt-dlp command with -vU flag added (yt-dlp -vU <your command line>)
• If using API, add 'verbose': True to YoutubeDL params instead
• Copy the WHOLE output (starting with [debug] Command-line config) and insert it below

[pukkandan]

Apparently, dict.get is unhashable in 3.7 😕

>>> {{}.get}
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: unhashable type: 'dict'

Wrapping it in a lambda works

>>> {lambda x: {}.get(x)}

... Can confirm the issue is fixed on my side, too, with latest "nightly" yt-dlp_x86.exe build:
