CKeditor 5 plugincollection Error in console

Nothing mentioned in the issue indicates this is specific to the ckeditor5_dev module. Does this issue only happen if the ckeditor5_dev is enabled?

Hi,

I think its core CKeditor 5 module installed in website. Sorry for mentioning the wrong version. Now i have attached the screenshots to understand the issue.
For that, we have created the 'Test HTML' for using the CKeditor 5 module. Once it is selected in Text format in content, showing console error.

Drupal version : 10.2.2

Thanks.

I have also been struggling with this issue on my Full HMTM editing profile. My Basic HTML is fine.

It happened after upgrading to CKEditor 5 in Drupal 10 from CKEditor 4 in Drupal 9.

For me, this involved upgrading the Anchor Link module from CKEditor 4 to a CKEditor 5 version.

I found that the library for Anchor link was not loading and throwing an error that basically crashed the JS interpreter and stopped all of the other JS from running. I would check to make sure that any additional plugins that your using on the text editing profile that is causing issues are not having conflicts.

Cheers,
Andrew

Thanks @awasson I had this same issue -- and indeed, I had also not installed the library. Once I got that in it started working again.

FYI here is another issue that results in plugin not found in case anyone stumbles across this: 📌 Support CKEditor5 45.x Active

This issue is probably better as closed as it seems unrelated to this module. The comments here pointing people to potential culprits for the unclear error is likely sufficient. Feel free to disagree of course
