Ajax error - Drupal.ckeditor5.saveCallback.has is not a function

This is probably because you applied a core patch:

https://www.drupal.org/project/drupal/issues/2741877 🐛 Nested modals don't work: opening a modal from a modal closes the original Needs work

The saveCallback.has only exists when applying the core patch for multiple modals. I'm working on a patch for this module as well, based on the issue https://www.drupal.org/project/ckeditor5_embedded_content/issues/3306230 ✨ It is not possible to have the embedded content modal open another modal. Needs review

thanks - correct, you are! Thanks for your work on this, great to see it come together :-)

You can now apply the core patch: this module should work with and without it.

Automatically closed - issue fixed for 2 weeks with no activity.
