AJAX error within WYSIWYG editor media button

The problem seems to be related to the Devel module. I needed to re-export some configuration and commit that to our project repo, so that when the configuration is imported, the configuration for Devel is correct.

Not sure why this caused an error but it's definitely not related to this module. Sorry about that.

I'm having the same issue, it seems to happen only if you're opening the media libary browser on a media reference field that isn't using the Media library extra field widget.

I had the issue in my project and was able to solve it by applying this patch on MR46.

Thanks

Here is a patch of this.

I've opened an MR with a smaller approach - what do you think @chr.fristch?

+1 for @alexpott's approach
