figure out what's broken with Vimeo on nextcloud.com

If I insert a Vimeo video on our homepage, I get loads of JS errors (see below). So I had to revert a commit moving the homepage go Vimeo: https://github.com/nextcloud/nextcloud.com/commit/62453a5495ceede3740e75748dd8c89b99bcc136
We do have to fix that but I can't - I have absolutely 0 javascript cluefulness.
The main JS loaded there that is unique is in these two files:
The errors I get:
