Yahoo财经历史数据爬取脚本报错：Malformed UTF-8 data stringify

我编写了一个用于爬取Yahoo财经历史数据的Google Apps Script脚本，但目前解密服务似乎失效了。脚本代码如下：

function Scrapeyahoo(symbol) {
  //modificación del 27/1/23 hecha por Tanaike 

  const s = encodeURI(symbol);
  const url = 'https://finance.yahoo.com/quote/' +s +'/history?p=' +s;

  var html = UrlFetchApp.fetch(url).getContentText().match(/root.App.main = ([\s\S\w]+?);\n/);
  if (!html || html.length == 1) return;
  var obj = JSON.parse(html[1].trim());
  var key = [...new Map(Object.entries(obj).filter(([k]) => !["context", "plugins"].includes(k)).splice(-4)).values()].join("");
  if (!key) return;
  const cdnjs = "https://cdnjs.cloudflare.com/ajax/libs/crypto-js/4.1.1/crypto-js.min.js";
  eval(UrlFetchApp.fetch(cdnjs).getContentText());
  const obj1 = JSON.parse(CryptoJS.enc.Utf8.stringify(CryptoJS.AES.decrypt(obj.context.dispatcher.stores, key)));
  const header = ["date", "open", "high", "low", "close", "adjclose", "volume"];
  const ar = obj1.HistoricalPriceStore.prices.map(o => header.map(h => h == "date" ? new Date(o[h] * 1000) : (o[h] || "")));
  
  return ar
}

执行时，在以下代码行出现错误：Malformed UTF-8 data stringify

JSON.parse(CryptoJS.enc.Utf8.stringify(CryptoJS.AES.decrypt(obj.context.dispatcher.stores, key)));

数周前@Tanaike曾解决过类似问题，但Yahoo财经似乎又有新的变更，现寻求该问题的解决方案，感谢帮助。
