Updated to Pleroma 2.1.0 - Cannot get remote emoji packs from other instances

When I go on admin-fe -> Emoji packs -> remote packs -> put an instance in the text box (https://fedi.absturztau.be/ for example), it loads the list of remote emoji packs, but when I click on them nothing happens.

Browser console shows this:

TypeError: Cannot read property 'forEach' of undefined
