title: UrlFetchApp and doPost(e), same code, different projects, different behaviors
body: <p>As I said in the title I got same code on frontend and backend test project (frontend: <code>UrlFetchApp</code> | backend: <code>doPost(e)</code>) and on dev project.</p>
  <p>As I'm quit new in Google Apps Script programming, I did a test project in one gmail account, in order to validate process like fetchUrlApp and doPost communication between two different spreadsheet. The dev project is on another account used as pre-production project.</p>
  <p>backend script is deployed as web app new version on both test and dev project
  post method is loading a sample basic JSON
  on test project I get my JSON on backend side but not on dev project.</p>
  <p>Here is the code and results</p>
  <p>backend doPost code :</p>
  <pre><code>function doPost(e) {
      Logger.log(&quot;I was called&quot;);
      if (typeof e != 'undefined');
      var data = JSON.parse(e.postData.contents);
      var ss = SpreadsheetApp.openById(&quot;my-backend-id&quot;);
      var sheet = ss.getSheetByName(&quot;Log&quot;);
      sheet.getRange(1, 1).setValue(JSON.stringify(data))
      //Logger.log(JSON.stringify(data));
      return ContentService.createTextOutput(JSON.stringify(e));
  };
  </code></pre>
  <p>frontend submit post request :</p>
  <pre><code>function test_rapide(){
    var data = {&quot;id&quot;:&quot;xyz&quot;,&quot;name&quot;:&quot;xy&quot;};
    var ret = makeRequest(&quot;https://my-web-app-URL/exec&quot;, data);
      
    var content = ret.getContentText();
    Logger.log(content);
  };
  </code></pre>
