Plugin Element in Group throwing errors

Hi all,

I built a rich text editor plugin for own use and it works fine as long as it’s not placed within a group.
On this page you can see two instance of the element: the to one is not in a group while the second one is in a group and doesn’t show the “content” field’s text “Type here…”. I tried other texts as well as dynamic values too, but nothing works.

However no errors are shown in the console, the Bubble debugger shows this error:

The plugin Custom Rich Text Editor threw the following error: TypeError: Cannot set property ‘innerHTML’ of undefined

Any idea what could be causing this issue? Thanks for any help in advance!
