کار با ckfinder در ckeditor

سلام من میخوام با ckfinder توی ckeditor5 فایل(از فایل های درون سرور) انتخاب کنم و بیارمش توی ادیتور. به محض اینکه روی ckfinder کلیک میکنم این خطا رو لاگ میکنه
TypeError: window.CKFinder is undefined

کدم به صورت زیر هست

<template>

       <ckeditor lan="fa" id="emailText" :editor="editor" @ready="onReady" v-model="emailText"
        :config="editorConfig"></ckeditor>              

</template>

<script>

    import axios_auth from "../../../axios_auth";
    import swal from "sweetalert";
    import DecoupledEditor from '@ckeditor/ckeditor5-build-decoupled-document';

    export default {
        name: "MailSend",
        data() {
            return {
                editor: DecoupledEditor,
                editorConfig: {
                    ckfinder: {
                        // Open the file manager in the pop-up window.
                        openerMethod: 'popup',

                        uploadUrl: 'https://mysite/api/v1/image/ckUpload?command=QuickUpload&type=Files&responseType=json',

                        options: {
                            resourceType: 'Images'
                        }
                    },
                }

            }
        },

        methods: {
            onReady(editor) {
                // Insert the toolbar before the editable area.
                editor.ui.getEditableElement().parentElement.insertBefore(
                    editor.ui.view.toolbar.element,
                    editor.ui.getEditableElement()
                );
        }
    }
</script>
