@Shabinder Just tested your playlist - everything seems ok. Please, check it again and provide your code snippet if error appears

from stackTrace Error Seems from JSON Parsing.
sealedtx commented 3 years ago

@Shabinder Your url returns:

This playlist type is unviewable.

Thats why it fails to parse json response. I may add additional checks for such bad pages, but common playlists should work fine, check it, please

Shabinder commented 3 years ago

@sealedtx Yeah , I tried that playlist is not viewable.

For me some are working and some Aren't

like this works: https://www.youtube.com/playlist?list=PLMRKdK25AuPVu7vuwjDm2yobPuZS8hiiO

but this Doesn't: https://www.youtube.com/playlist?list=RDCLAK5uy_nwqiuZ17rDNJGTtN-ihrJNLPyl1XWh-7c

sealedtx commented 3 years ago

@Shabinder This is another error, I will look

sealedtx commented 3 years ago

@Shabinder The problem was: extracting number of views from text "No views". Both problems are fixed and just released in 2.4.6

Shabinder commented 3 years ago

@sealedtx Thanks for your contributions , will try new release later tonight

Shabinder commented 3 years ago

Yeah All working gr8. Closing this issue.
