CKEditorError: plugincollection-plugin-not-found

Thank you for reporting the bug and for providing a possible fix.

I suspect the true source of this bug is a missing dependency.

Thanks for the quick response! Yeah it seems all the other CKEditor plugins were unavailable for loading so the whole thing crashed :/

This patch worked for me.

Seemed to be a conflict with CKEditor5 Fullscreen module, as uninstalled that module also resolved the issue.

This patch worked for me.

I second @damienmckenna. It looks like a missing dependency. I tested around with the most likely suspects. It turned out setting ckeditor5/internal.admin.image as a dependency seems to fix the error.

I created a MR + here's the attached patch. Thanks for a review.

Replaced patch from #2 with patch from #9 and works great.

Thank you!

The problem is with JsCollectionGrouper. When JS files are aggregated, say there are like 100 js files, they get grouped based on the library dependencies. Those 100 js files may be spit up into 5 groups of js files which ends up as 5 big JS files wrapped in an anonymous function to scope them altogether.

All the CKEditor plugins like alignment and bold and ckeditor_media_resize are their own separate JS files. Those little files aren’t being aggregated into the same larger aggregated JS file. You can tell this is true because when you turn off JS aggregation the files can see each other again and the error goes away.

When we set preprocess: false we are forcing a new group (aggregated JS file).

The fix committed as well as patch #9 don't work for me, the only thing that works is patch #2, I don't know why.

Thanks for trying it. Do you have other JS libraries in your site that have preprocess: false in the definition? Try removing those and clearing caches if you do. I noticed editor_advanced_link does it too. You may be able to debug JsCollectionGrouper and see what the offending library is that is putting ckeditor_media_resize in a group outside of the rest of the ckeditor libraries.

Yes I am using "editor_advanced_link" module too, so does this mean that we should open an issue in "editor_advanced_link" in order to the preprocess: false to be removed ?

Yes, especially if it fixes your error. Did it?
