title: java.lang.nullpointer exception in jmeter in Non-GUI mode
body: <p>When i try to execute my Jmeter (version 5.3) recorded script in Non-GUI mode, using a remote server, it displays a &quot;java.lang.NullPointerException&quot; while generating the dashboard(HTML) report. Also, my CSV file (or jtl report) is creating an empty file without any data.</p>
  <p>I have used loop controller to call my http request .
  I have added sample variables to my jmeter.properties file so that they can be recorded.
  Also , I have set &quot;jmeter.save.saveservice.output_format=csv&quot; in properties file.</p>
