无法在Google Apps脚本中解析来自UrlFetchApp的数据

我当前的Cloud Run URL返回一个长字符串，与此处所述的确切格式匹配。

当我在Google Apps脚本中运行以下代码时，我得到的日志输出为“ 1”。发生的情况是，整个字符串被放置在data数组的[0] [0]位置，而不是被实际解析。

function myFunction() {
const token = ScriptApp.getIdentityToken();
const options = {
  headers: {'Authorization': 'Bearer ' + token}
}
var responseString = UrlFetchApp.fetch("https://*myproject*.a.run.app", options).getContentText();
var data = Utilities.parseCsv(responseString, '\t');
Logger.log(data.length);
}

我的预期输出是上述链接中所述的2D数组，记录的输出长度为18。

我已通过以下方式确认了我的回复输出：

1. 记录 responseString
2. 将输出日志复制到单独的var-> var temp = "copied-output"
3. 将parseCsv行更改为-> var data = Utilities.parseCsv(temp, '\t')
4. 保存并运行新代码。然后输出一个成功的2D数组，长度为18。

那么，为什么我的当前代码不起作用？很高兴尝试任何事情，因为我没有主意。

Python脚本代码

@app.route("/")
def hello_world():
    # Navigate to webpage and get page source
    driver.get("https://www.asxlistedcompanies.com/")
    soup = BeautifulSoup(driver.page_source, 'html.parser')

    long_string = ""

    for row in soup.select('tr'):

        else:
            tds = [td.a.get_text(strip=True) if td.a else td.get_text(strip=True) for td in row.select('td')]
            count = 0
            for column in tds:
                if count == 4:
                    linetext = column + r"\n"
                    long_string = long_string+linetext
                else:
                    text = column + r"\t"
                    long_string = long_string+text
                    count = count+1
            limit = limit+1
        
    return long_string

GAS代码已修改：

function myFunction() {
const token = ScriptApp.getIdentityToken();
const options = {
  headers: {'Authorization': 'Bearer ' + token}
}
var responseString = UrlFetchApp.fetch("https://*myfunction*.a.run.app", options).getContentText();
Logger.log("The responseString: " + responseString);

Logger.log("responseString length: " + responseString.length)

Logger.log("responseString type: " + typeof(responseString))
var data = Utilities.parseCsv(responseString, '\t');
Logger.log(data.length);
}
