    Hi!

     

    Thank you for answering so fast! But what I posted was not the real response but only a mock so that I could explain what the problem was (As I cannot publish online the real response) so that didn't work for me.

     

    Today I tried something else and it worked. Here is I used in my script:

    import groovy.json.JsonSlurper
    def response=messageExchange.response.responseContent
    def json=new JsonSlurper().parseText(response)

    if (json.registers.name){

    def first=context.expand('${testStepName#Response#$[\'registers\'][\'name\'][\'first\']}')

    assert first!=null

    }

     

    I can't figure out why the first script didn't work and returned null but this solution is working for me and I get the right value from the response.

I copied your response and your groovy script assertion, and I do not get a failure for first being null. When I run it, it passes fine. I even included a statement that would fail if first was anything OTHER than "George", and it ran without issue. 

 

if (first != "George")
	{
		assert false;
	}
