CKEditor field in Category Set fails to load in the CMS due to JS error

[JazzMusic131]

Description

When trying to add a CKEditor field to a Category set, with a Link type added to the toolbar, the field does not load in the CMS during content entry due to the following JS error:

Uncaught (in promise) TypeError: this._linkUI._createToolbarLinkButton is not a function
    at n.value (linkui.js:57:20)
    at n.value (linkui.js:41:10)

If the Link field is removed from the CKEditor config's toolbar, the error is not present and the field loads as expected in the CMS.

Steps to reproduce

1. Create a new category set in Craft
2. Add a CKEditor field with a Simple config that includes the Link type in the toolbar
3. Add the CKEditor field to the category set's field layout
4. Create or edit a category in the category set in the CMS

Additional info

• Craft version: 5.7.8.2
• PHP version: 8.2
• Database driver & version: MySQL 8.0 (DDEV)
• Plugins & versions: CKEditor version 4.9.0

Hi, thanks for reaching out!
Do you have any modules or plugins that use the craft\ckeditor\Field::EVENT_DEFINE_LINK_OPTIONS? In your "Simple" CKEditor config, do you have any custom settings in the "Config Options" field?
I can trigger this error if (via either of the above methods) I modify the linkOptions to be empty.

I just raised a PR to safeguard against that error.

@i-just Ok, oddly enough, I just restarted my DDEV env for the project today, went back in and tried to add the Link to the toolbar and now it works:

I didn't update any plugins or make any additional adjustments; very strange. I guess this can be closed out then!

Thanks for the update! Glad it’s all working for you now 🙂

I’ll keep it open for now, as I think the PR I raised based on your report is still worth considering.

@i-just I'm running into this error. Can you can the PR reviewed and merged?

CKEditor 3.14.0 and 4.10.0 are out with the fix for this. Thanks again!
