Ytm-extractor: Import YouTube Music listens to ListenBrainz

Has anyone had success with this ytm-extractor for submitting historical YouTube watch data into ListenBrainz? I’ve been having issues getting a complete watch-history.json export from Google Takeout (it’s truncated at 6 MB while my watch-history.html file is 60 MB). I’m hoping to use this to import my historical YouTube watch data, when I’ve watched music videos or listened to music through the YouTube app on my TV (not through YouTube Music).

I ran it on Linux and it worked! It did however quit after showing the following,

from 1606625393 to 161497315

Do I need to worry that it didn’t submit all the listens to ListenBrainz?
