我正在尝试基于服务器RESTAPI响应(八位字节流)创建工作簿,但创建失败

以下是“创建工作簿”函数的代码段:

async function createWorkbookFromExisting(myBlob) {

  OfficeExtension.config.extendedErrorLogging = true;
  const reader = new FileReader();
  reader.onload = (event) => {
    Excel.run((context) => {
    // strip off the metadata before the base64-encoded string
    const startIndex = reader.result.toString().indexOf("base64,");
    console.log(startIndex);
    const mybase64 = reader.result.toString().substr(startIndex + 7);
    //console.log(mybase64);
  Excel.createWorkbook(mybase64);
  return context.sync();
});
};
下面是我的blob创建片段:

xmlHttpRequest.onreadystatechange = function() {
  //var a;
  if (xmlHttpRequest.readyState === 4 && xmlHttpRequest.status === 200) {
    console.log(xmlHttpRequest.response);
    var respObj = new Object(xmlHttpRequest.response);
    //xmlHttpRequest.re
    console.log(respObj);
    var resp = new Blob([xmlHttpRequest.response], { type: 'application/ vnd.openxmlformats - officedocument.spreadsheetml.sheet;'});
    
    createWorkbookFromExisting(resp);
    
    
  }
};
xmlHttpRequest.open("GET", _url);
//xmlHttpRequest.setRequestHeader("Content-Type","application/octet-stream");
xmlHttpRequest.responseType = 'blob';
xmlHttpRequest.send();
我有一个错误:
