            }
        ]
    }
}

I received the following response

I found the JSR223 Assertion with script language javascript to be the easiest. at least if you have knowledge in java and javascript. And no need to add any plugins.

My working code in detail:

var json = JSON.parse(SampleResult.getResponseDataAsString());
if (json.statusCode != 200) {
    AssertionResult.setFailureMessage("" 
        + json.statusCode 
        + " " + json.statusMessage
        + " " + json.errorMessage);
    AssertionResult.setFailure(true);
}

I personally prefer to use BSF PostProcessor in coupling with Groovy language. Example of how to parse JSON with Groovy you can find here how to parse json using groovy

For start following JSONPath Assertion will test your statusCode
