i don't see any errors. although, i don't see the channel neither.

as far as i understand, you talking about YouTubeButton script.

there are 2 problems: when the 2nd problem is solvable, the 1st one is probably somewhere on the google side (like old api etc).
 * 1) at 2018, script was reported as non-working (see the "bugs" section)
 * 2) the script itself is not supposed to work in the community corner

i'd suggest to report the problem on the talk:YouTubeButton or on the authors talk page, in case of author doesn't read the forum.
