Cant use nodetype in english dimension

[koehlerannkathrin]

I have two language dimensions (DE and EN) in my project. In the backend with german dimension selected i can add the Better-Embed Nodetype and also add a link. If I switch to the English dimension, I cannot add the better embed element there.
It doesn't matter if I create the page with "create and copy" or if I have set a default language (de) and change it that way. Unfortunately, it doesn't work in either case.

This is error i get after add the better embed nodetype to my content tree, insert a URL and create the element.

After i delete "BetterEmbedRepository::BETTER_EMBED_ROOT_NODE_NAME" in the referenced file and line i can add the element as expected. Maybe this helps by debugging.
