异步customFunctions在启动时引发意外的消息类型

我有一个CustomFunctions javascript,它可以完美地与同步函数配合使用,但只要我尝试使用异步函数,我就会得到:

中第21行第707859列出现未处理的异常 https://appsforoffice.microsoft.com/lib/beta/hosted/excel-win32-16.01.js 0x800a139e-Der optstod en JavaScript krselsfejl:意外的消息类型

“” 这发生在对我的js文件调用任何javascript代码之前。消息类型是1002,因此如果在excel-win-16.01中指定的位置使用javascript,那么当然会抛出错误。js公司: “”

if(i[t).messageType==1001)u.push(i[t]);否则抛出OfficeExtension。公用事业createRuntimeError(st.generalException,“意外消息类型”, “”

函数的json描述为:

    {
      "name": "helloasync",
      "description": "simple test string return",
      "helpUrl": "https://www.konsolidator.com",
      "result": { 
        "type": "string",
        "dimensionality": "scalar"
      },
      "parameters": [],
      "options": {"sync": false}
    },
        {
      "name": "ADD42ASYNC",
      "description": "asynchronously wait 250ms, then add 42",
      "helpUrl": "http://dev.office.com",
      "result": {
        "type": "number",
        "dimensionality": "scalar"
      },
      "parameters": [
        {
          "name": "num",
          "description": "Number",
          "type": "number",
          "dimensionality": "scalar"
        }
      ],
      "options": {
        "sync": false
      }
    }

JS代码:

function helloasync() {
    return new OfficeExtension.Promise(function (setResult) {
        setTimeout(function () {
            setResult("hello");
        }, 1000);
    });
}

function ADD42ASYNC(num) {
    // waits 1 second before returning the result
    return new OfficeExtension.Promise(function (resolve,reject) {
        //resolve(num);
        //reject(num);
        setTimeout(function () {
            resolve(num + 42);
        }, 1000);
    });
}

我所有的异步CustomFunction都失败了! 边栏异步函数与同步函数一样正常工作。
