如何將RTF格式文件（.rtf）文件內容插入word文檔中使用word javascript API

Question

我正在使用word javaScript API來開發Word插件，我需要從服務器加載文件並將內容插入到文件，目前.DOCX文件工作正常，並插入到文檔中，但是當我嘗試將.RTF格式文件的內容插入到文檔時，Word會引發以下錯誤：

Error: {"name":"OfficeExtension.Error","code":"RunMustReturnPromise","message":"The batch function passed to the \".run\" method didn't return a promise. The function must return a promise, so that any automatically-tracked objects can be released at the completion of the batch operation. Typically, you return a promise by returning the response from \"context.sync()\".","traceMessages":[],"debugInfo":{},"stack":"RunMustReturnPromise: The batch function passed to the \".run\" method didn't return a promise. The function must return a promise, so that any automatically-tracked objects can be released at the completion of the batch operation. Typically, you return a promise by returning the response from \"context.sync()\".\n at t.throwError (https://appsforoffice.microsoft.com/lib/beta/hosted/word-win32-16.01.js:21:233250)\n at Anonymous function (https://appsforoffice.microsoft.com/lib/beta/hosted/word-win32-16.01.js:21:202009)\n at yi (https://appsforoffice.microsoft.com/lib/beta/hosted/word-win32-16.0 

我使用下面的代碼插入內容：

range.insertFileFromBase64(myBase64, Word.InsertLocation.start); 

請教我如何插入RTF格式的文件內容在word文檔中。 謝謝。

今天API不支持插入RTF文件，請嘗試docx格式。 Btw你的錯誤似乎是你沒有調用return context.sync（）。
