SyntaxError：意外令牌：json.parse处为T

Question

I'm new to google scripts and I want to fetch data from an URL when the user is logged in. I wrote some code but when I execute it the following error appears: SyntaxError: Unexpected token: T

I know that this question has been asked before, but I can't find a solution for my issue...

function myFunction() {
  var endpoint = 'rule-sets';
  var url = 'https://example.com/api/'+endpoint;
  var restHeaders = {    
    'X-Application-Key': 'f3ez1a48f06838b7238z20cff80e010bf0c42cfp',
    'Authorization':'Bearer bm9scnVuMDQ4Z2FvaWpvdHBqa2Y1djA5WWavTiElV5DyYjdxb3UxNnVyMzRoNWhsISPBmXNyZDFtMCYzMDk2JjE0NjE5MDI3NTYwODI=',
  }
  var options = {
    'method' : 'get',
    'headers': restHeaders, 
    'muteHttpExceptions': true,
  };
  var urlResponse = JSON.parse(UrlFetchApp.fetch(url, options));
  Logger.log(urlResponse);
  Logger.log(urlResponse.data.length);
}

Looking at https://developers.google.com/apps-script/reference/url-fetch/url-fetch-app#methods signature it looks like it will be this:

var urlResponse = UrlFetchApp.fetch(url, options);
var jsonContent = JSON.parse(urlResponse.getContentText());
Logger.log(jsonContent);
Logger.log(jsonContent.data.length);

You were parsing the return value of fetch which is an object.
