Description

when trying to download videos the downloader will no longer get the thumbnail image or the uploader nickname.

Probably related: I am also not able to use the output format %(upload_date)s, so the Upload data metadata seems to be missing too.

Log showing error while using %(upload_date)s:

Edit the log shows version 2020.06.06, but I'm running from the latest master, d84b21b

Playlists with multiple pages also dont download now. All these problems started happening at the same time. It seems like something changed in youtube's end

[tyzoid]

@pukkandan That was solved in commit d84b21b which is already in master.

@tyzoid when will be fixed downloadable release?
