Unable to add first party Special Character Plugin

[twitcher07]

Description

I am trying to add the Special Character plugin that is a first party plugin but I am getting the below error in the javascript console when editing the CKeditor config in craft:

special-characters.js?v=1737491694:5 Uncaught (in promise) TypeError: t is not a constructor
    at S._createDialogButton (special-characters.j…=1737491694:5:15907)
    at Object.callback (special-characters.j…=1737491694:5:14449)
    at to.create (ckeditor5-dll.js?v=1737491694:2:551656)
    at ToolbarBuilder.js:46:38

and the config editor looks like this:

Here is my asset bundle that should be enabling the plugin:

<?php

namespace modules\CkeditorCustom\src\assets;

use Craft;
use craft\ckeditor\web\assets\BaseCkeditorPackageAsset;

/**
 * Ckeditor Customizations asset bundle
 */
class CkeditorCustomAsset extends BaseCkeditorPackageAsset
{
    public $sourcePath = '@modules/CkeditorCustom/assets';
    public $depends = [];
    public $js = [
        'js/mention.js',
        'js/special-characters.js'
    ];
    public $css = [];
    public array $pluginNames = [
        'Mention',
        'SpecialCharacters',
        'SpecialCharactersEssentials'
    ];
    public array $toolbarItems = [
        'specialCharacters'
    ];
}

Let me know if you need any more information.

Steps to reproduce

1. Add Special Character plugin through a custom module.
2. Navigate to CKeditor config editor in craft console.

Hi, thanks for getting in touch! Which version of the Special Characters package did you use? The latest version of Craft’s CKEditor plugin (4.4.0) uses CKEditor 41.0.0, so I’d first try doing what you’re doing with version 41.0.0 of the Special Characters package.

@i-just I was using Version 44.1.0 of the @ckeditor/ckeditor5-special-characters package. I will try the 41.0.0 version of the package and report back.

Sounds good! As it might matter in your case, yesterday, we released version 4.5.0 of the plugin (it requires Craft 5.6.0 or higher) which uses CKEditor 5 44.0.0.

@i-just ok thanks for letting me know.

I can confirm I used the 41.0.0 version of the special characters package it that fixed the issue.

Thanks for the update. Glad you got it working!
