如上图，插入文本出现这个错误，插入代码如下
const DocumentRange = await app.ActiveDocument.GetDocumentRange()
// 获取末尾
const pos = await DocumentRange.End
await app.ActiveDocument.Range.SetRange(pos, pos)
const range = await app.ActiveDocument.Range(pos, 100000000)
await app.ActiveDocument.ActiveWindow.ScrollIntoView(range);
// .SetRange(end)
// console.log(End, DocumentRange);
range.Text = element
await range.Text
await range.PasteHtml({
HTML: '内容'
})
