CKEditor tools not able to pass back a response

Could you check your logs if you find some error? It looks like a network error in the console.

So at /admin/reports/dblog

Yes, you are right, two warnings and an error in this precise order...

But no other network problems of any kind that I notice.

Linking to a related issue that will replace the CKEditor UI with native Drupal.

Hi,
Tested ckeditor5 with latest dev and the dropdown behaves differently depending of the text format.
With fullhtml format the local llm started to generate something and the writer became idle,
but the response never came back to the text box.
With another text format the local llm did not even start doing anything even all settings looked to be similar.
On the sidebar all looks to be working

@anaconda777 - moved your question to a new issue here and will close this issue since its outdated: https://www.drupal.org/project/ai/issues/3484046 🐛 ckeditor5 with latest dev and the dropdown behaves differently depending of the text format Active
