如何使用 word javascript API 将富文本格式（.rtf）文件内容插入 word doc

Question

我正在使用 word javaScript Api 开发 Word 插件，我需要从服务器加载文件并将内容插入到文档中，目前 .docx 文件工作正常并插入到文档中，但是当我尝试将 .rtf 格式的文件内容插入到文档中，word 会抛出以下错误：

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

我正在使用以下代码插入内容：

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

请告知我如何在 Word 文档中插入 RTF 格式的文件内容。 谢谢。

目前 API 不支持插入 RTF 文件，请尝试使用 docx 格式。 顺便说一句，您的错误似乎是您没有调用 return context.sync()。
