  I have the following method I want to test using PostMan 
  <p><code>public returnType name( String var1, String var2,String var3, String var4);</code></p>
  <p>I tried to send a post request to test I sent one like this but it does not work:</p>
  <pre><code>{
      &quot;var1&quot;: &quot;GU4777&quot;,
      &quot;var2&quot; : &quot;HU 888&quot;,
      &quot;var3&quot; : &quot;NU 8890&quot;,
      &quot;var4&quot; : &quot;UJ 9909&quot;
   }
  </code></pre>
  <p>I get this error: <br/>
