Unable to see Response Body in JMeter, View Results Tree listener

Question

When I run a Http Request, to a page that should return a response body (I know it's working because I already tried in Postman). When I execute the sampler it's sends a 200 OK code, but the response body in the View Results Tree Listener, is empty. Why does this happen?

I use MAC OS, and I installed JMeter with Brew. I've already tried to add the following information in the user.properties file:

jmeter.save.saveservice.output_format=xml
jmeter.save.saveservice.response_data=true
jmeter.save.saveservice.samplerData=true
jmeter.save.saveservice.requestHeaders=true
jmeter.save.saveservice.url=true
jmeter.save.saveservice.responseHeaders=true

It looks like this:

The changes you've made don't have any impact onto View Results Tree listener output, they are only for .jtl results files.

Try the following:

1. Run your JMeter test in command-line non-GUI mode like

   jmeter -n -t test.jmx -l result.xml
   

   and open result.xml file with your faviourite text or XML viewer/editor. You should see something like:

   <?xml version="1.0" encoding="UTF-8"?>
   <testResults version="1.2">
       <httpSample t="93" it="0" lt="93" ct="42" ts="1568029799118" s="true" lb="HTTP Request" rc="200" rm="OK" tn="Thread Group 1-1" dt="text" by="759" sby="139" ng="1" na="1">
           <responseData class="java.lang.String">{
               &quot;userId&quot;: 1,
               &quot;id&quot;: 1,
               &quot;title&quot;: &quot;delectus aut autem&quot;,
               &quot;completed&quot;: false
               }</responseData>
           <java.net.URL>http://jsonplaceholder.typicode.com/todos/1</java.net.URL>
       </httpSample>
   
   </testResults>
   

   where responseData tag contains XML-escaped response data. If there is some data in the file - most probably something is wrong with your JMeter installation, try re-installing it by downloading JMeter from the official website as the Brew package might be broken.

2. Check jmeter.log file contents, if anything goes wrong JMeter normally writes a log message with the results.
