That did the trick! Thank you! Can be closed, works as expected.
Dear Vincent,
Thank you for verifying. Your F12 tip gives me more insight. It is indeed throwing some errors, and I think I found out why.
In the F12 console:
Value: /modules/contrib/ckeditor5_template/template/ckeditor5_template.json.example
GET https://gigview.be/modules/contrib/ckeditor5_template/template/ckeditor5_template.json.example 404 (Not Found)
SyntaxError: Unexpected token '<', "<!DOCTYPE "... is not valid JSON
Debugging can be done with an unminified version of CKEditor by installing from the source file. Consult documentation at https://www.drupal.org/node/3258901
TypeError: Cannot read properties of undefined (reading 'forEach')I'm however still in testing phase of my website on a subdomain: gigview.be/d10. So the GET should come from https://gigview.be/d10/modules/contrib/ckeditor5_template/template/ckedi...
When I try to add "/d10" before the Template path in the configuration, it says "template file not found", it only accepts as of /modules
Any suggestion or workaround to get this working?
Not solved at all, but a much easier way I got Youtube, Spotify etc. working in the CkEditor:
https://www.drupal.org/project/ckeditor5_media_embed →
It uses the CkEditor package described (and demo'd) here: https://ckeditor.com/docs/ckeditor5/latest/features/media-embed.html
For all those not getting this URL Embed working: Drupal module CkEditor 5 Media Embed (still in beta) does the trick, with just 1 module! No dependencies, complicated installs or other shenanigans, just right out of the box a ckeditor button that lets you insert youtube, Spotify etc. links and it gives you a responsive media!
