CKEditorError: selection.getFirstPosition() is null after 10.3 update

I got the same error when i migrate to Drupal 10.3

angheloko → closed merge request !7

angheloko → closed merge request !8

Works for me.
Thank you.

We are having this issue also with 3.0.0-beta1. Our console error is slightly different:

TypeError: Cannot destructure property 'parent' of 'selection.getFirstPosition(...)' as it is null.

I have same error with drupal 10.3

I can also confirm that the merge request resolves the issue!

This seems to be a common issue with plugins, such as https://www.drupal.org/project/ckeditor_bs_grid/issues/3389827 🐛 conflict with CKEditor5 Show Block Fixed , and checking for the existence of the object is the resolution.

The input field is empty when this error is happening, Major if not critical so bumping the Priority.

+1 RTBC

I can also confirm that the merge request resolves the issue for D10.3

Made a patch for those still facing this issue with version 3.0.x.

Hi Donpas,

There is a MR available. You can find the patch by clicking on "plain diff".

hello,
We encountered the same problem when updating core 10.3.
we had ckeditor_iframe in alpha1

By updating ckeditor_iframe and using the patch in comment #18, ckeditor works again.

Patch from #18 works for me.. RTBC IMHO

I've applied the MR!9 as patch and it applied successfully with no errors.

Tested on Drupal 10.3.2 with drupal/ckeditor_iframe: ^3.0@beta

Thanks
