JS Error when loading CKeditor 5 with active Highlight Plugin under Drupal 10.1

I am getting the same error with Drupal 10.1.5!

I fixed this by re-building the highlight.js file with the new version of "@ckeditor/ckeditor5-highlight": "~40.0.0" and "@ckeditor/ckeditor5-theme-lark": "~40.0.0", "ckeditor5": "~40.0.0" in the package.json file.

Hope to get this fixed in this module. Thanks!

I am getting the same error on Drupal 10.1.5. The fixes mentioned in #3 works perfectly fine.
Verified if the fixes are compatible with Drupal 9.5.11. It isn't working. Throwing error

Checking if any possible fixes for both Drupal 9 and 10.

Created MR 2 https://git.drupalcode.org/project/ckeditor5_highlight/-/merge_requests/2 from @jmcintyre's commit.

I think we should match 10.1 core's ckeditor5 version, which is 39

And yes, that won't work for <10.1, so this have to go to 1.1.x branch

Changed package.json dependencies to version 39.0.0, and target branch in the MR to 1.1.x. Looks like 1.1.x is behind 1.x right now, so can change target branch back if needed.

Also, rebuilt the JS, but there's no difference between the 40 build and 39 build.

Using plain diff from MR 2 as a patch works to make the button work here :)

Automatically closed - issue fixed for 2 weeks with no activity.
