Angular中的CKEditor . TypeError：在insertText之后无法读取null的属性'type'

我正在构建一个应用程序，我在Angular框架中使用CKEditor .

无论如何 - 一切正常，但当我试图调用函数insertText时，我有以下错误：

edit.html：180错误TypeError：无法读取（ckeditor.js：139）属性'type'的位于CKEDITOR.dom.range.createBookmark2（ckeditor.js：141）的Array.createBookmarks2（ckeditor.js： 487）at CKEDITOR.dom.selection.createBookmarks2（ckeditor.js：440）at CKEDITOR.plugins.undo.Image（ckeditor.js：1081）at CKEDITOR.plugins.undo.UndoManager.save（ckeditor.js：1076）at一个 . （ckeditor.js：1072）at a（ckeditor.js：10）a.CKEDITOR.event.CKEDITOR.event.fire（ckeditor.js：12）at a.CKEDITOR.editor.CKEDITOR.editor.fire（ckeditor . js：13）View_PageEditComponent_3 @ edit.html：180 DebugContext_.logError @ services.ts:571 ErrorHandler.handleError @ error_handler.ts:69 next @ application_ref.ts:366 schedulerFn @ event_emitter.ts:96 SafeSubscriber .__ tryOrUnsub @ Subscriber.ts ：252 SafeSubscriber.next @ Subscriber.ts:204 Subscriber.next @ Subscriber.ts:135 Subscriber.next @ Subscriber.ts:95 Subject.next @ Subject.ts:61 EventEmitter.emit @ event_emitter.ts:78 NgZone.triggerError @ ng_zone.ts:87 onHandleError @ ng_zone.ts:283 ZoneDelegate.handleError @ zone.js：385 Zone.runTask @ zone.js：184 ZoneTask.invoke @ zone.js：476 ERROR CONTEXT DebugContext {view：Object，nodeIndex： 137，nodeDef：Object，elDef：Object，elView：Object} component：（...）componentRenderElement：（...）context：（...）elDef：ObjectelOrCompView：（...）elView：Objectinjector :( . ..）nodeDef：ObjectnodeIndex：137p roviderTokens：（...）引用：（...）renderNode：（...）view：Object__proto__：Objectcomponent：（...）componentRenderElement：（...）context：（...）elOrCompView :( . ...）inject：（...）logError：function（console）providerTokens：（...）references：（...）renderNode：（...）constructor：function DebugContext_（view，nodeIndex）get component：function （）get componentRenderElement：function（）get context：function（）get elOrCompView：function（）get injector：function（）get providerTokens：function（）get reference：function（）get renderNode：function（）proto：Object View_PageEditComponent_3 @ edit .html：180 DebugContext_.logError @ services.ts:571 ErrorHandler.handleError @ error_handler.ts:69 next @ application_ref.ts:366 schedulerFn @ event_emitter.ts:96 SafeSubscriber .__ tryOrUnsub @ Subscriber.ts:252 SafeSubscriber.next @ Subscriber .ts：204 Subscriber.next @ Subscriber.ts:135 Subscriber.next @ Subscriber.ts:95 Subject.next @ Subject.ts:61 EventEmitter.emit @ event_emitter.ts:78 NgZone.triggerError @ ng zone.ts：87 onHandleError @ ng_zone.ts：283 ZoneDelegate.handleError @ zone.js：385 Zone.runTask @ zone.js：184 ZoneTask.invoke @ zone.js：476

这是我的CKEditor选择器：

<ckeditor
        name="content"
        id="content"
        [(ngModel)]="page.content"
        debounce="500"
        [config]="{
                                                skins: 'minimalist',
                                                allowedContent: true,
                                                extraPlugins: 'divarea',
                                                contentsCss: CKECSS
                                            }"
        (ready)="setCkeObject($event)"
        (focus)="setCkeObject($event)"
        (blur)="setCkeObject($event)"
        #ckeEditor
>
</ckeditor>

我的editComponent TypeScript的一部分：

setCkeObject($event) {
        this.ckeObject = $event;
    }

insert_shortcode(shortcode) {
        if (this.ckeObject != null && this.ckeObject.editor != null) {
            this.ckeObject.editor.insertText(shortcode);
            this.alertService.addAlert('success', 'alerts.file_added_at_the_content_cursor_position');
        } else {
            this.page.content += shortcode;
            this.alertService.addAlert('warning', 'alerts.sorry_something_gone_wrong');
        }
    }

问题是，有时候它正在工作，有时它不会 .

来自ckeditor.js的代码导致了这个问题（第6行）：

createBookmark2: function() {
                function a(b) {
                    var e = b.container, d = b.offset, f;
                    f = e;
                    var g = d;
                    f = f.type != CKEDITOR.NODE_ELEMENT || 0 === g || g == f.getChildCount() ? 0 : f.getChild(g - 1).type == CKEDITOR.NODE_TEXT && f.getChild(g).type == CKEDITOR.NODE_TEXT;
                    f && (e = e.getChild(d - 1),
                    d = e.getLength());
                    if (e.type == CKEDITOR.NODE_ELEMENT && 0 < d) {
                        a: {
                            for (f = e; d--; )
                                if (g = f.getChild(d).getIndex(!0),
                                0 <= g) {

                                    break a
                                }
                            d = -1
                        }
                        d += 1
                    }

                        d = g ? g.getIndex(!0) + 1 : 0))
                    }

                        0 >= a.offset && (a.offset = d.getIndex(),
                        a.container = d.getParent()))
                    }
                }

            }(),
