well, our error is just a subsequent error.
(And a missing function is just ignored)
If we look closely into the log, we see the "real" problem:
Quote:bad http response: 401 forbidden
which means, that the TMDB did not allow your call.
Since it works here, you might have hit some connection limit and TMDB does stop you?
Does it work now?
Does it work inside Kodi?
Since the universal scraper has so many settings... could you upload the data/scraper_metadata.universal.conf from TMM dir? (check if there are no personal OMDB keys or similar in there) so we can replicate your config?
Edit:
If i execute the your call in browser, i'll get a "Suspended API key: Access to your account has been suspended, contact TMDb." error message.
But your used API key is not the same, as mine - although it seems, we both use Universal Movie Scraper 4.0.2 ?!?
Try deleting/updating that plugin from Kodi....
