title: Jmeter Keycloak Authorization_code
body: <p>Im currently trying to load test a website with keycloak authorization.
  The problem is that i cant find the authorization code anywhere in the previous https requests, so i cant use the regular expression extractor to grab it and turn it to a dynamic variable. So how do i configure it to be dynamic?

  <p>i already turned to session_code, tab_id and executive into dynamic variables, but it still returns &quot;{&quot;error&quot;:&quot;invalid_grant&quot;,&quot;error_description&quot;:&quot;Code not valid&quot;}&quot;</p>
