为什么此脚本会发送损坏的 PDF？

Question

我已将我的代码重写为，但它并没有解决我脚本的问题。它发送带有 pdf 附件的电子邮件，我没有收到任何错误，但我无法打开该文件。我已经尝试了 Whosebug 上发布的多种解决方案。

什么可能导致 pdf 在发送后损坏？我重组了我的 url，但运气不好。

function emailPDF() {

SpreadsheetApp.flush();

var ss = SpreadsheetApp.openByUrl('url')
var sheet = ss.getSheetByName('Reviews Due');

var row = 2;
var col = 2;

var test = sheet.getRange(row,col).getValue();

if (test == "New Employee Reviews"){

var token = ScriptApp.getOAuthToken();
var params = {
  headers: {
    'Authorization': 'Bearer ' + token,
  },
  'muteHttpExceptions' : true
};

var sheetId = sheet.getSheetId();

var url_base = "https://docs.google.com/spreadsheets/d/" + ss.getId() + "/" + "export?";

var url_ext = 'exportFormat=pdf'
+ '&format=pdf'
+ '&gid=' + sheetId
+ '&size=letter'
+ '&portrait=false'
+ '&fitw=true'
+ '&sheetnames=false'
+ '&printtitle=false'
+ '&pagenumbers=false'
+ '&gridlines=false'
+ 'fzr=false';

var response = UrlFetchApp.fetch(url_base + url_ext, params);
var blob = response.getBlob().setName("Reviews Due" + ".pdf");

这是点差urlsheet： https://docs.google.com/spreadsheets/d/1wmnw9Nl6B0e8IgVDgTEtGLzWhh1ssSgCLiOMsgs6Z64/edit#gid=1633156004

这是我将 sheet 导出为 pdf 时的 url： file:///C:/Users/gwaldo/Downloads/Master%20Progression%20Schedule%20-%20Reviews%20Due.pdf

当我更改 blob 变量以包含 getAs() 时，这里是它导出的 pdf：non corrupted pdf, but no data

Logger.log(url_base + url_ext) = https://docs.google.com/spreadsheets/d/1wmnw9Nl6B0e8IgVDgTEtGLzWhh1ssSgCLiOMsgs6Z64/export?Format=pdf&format=pdf&gid=1633156004&size=letter&portrait=false&fitw=true&sheetnames=false&printtitle=false&pagenumbers=false&gridlines=falsefzr=false

400 根据 RFC2616 的状态代码是

10.4.1 400 Bad Request

The request could not be understood by the server due to malformed syntax.

似乎有一个查询参数的语法无法理解或格式不正确。只需添加 var url_ext='format=pdf' 即可帮助隔离问题。通过 OP 测试每个参数后，似乎 fzr=false 导致了问题，因为它在
