Unexpected 500 response code during execution

Gatling (Open-Source)

I’m executing below code and even when there is no check for status getting unexpected 500 status as status.find.in([200, 209], 304), found 500

package collectionApis;

import io.gatling.javaapi.core.*;
import io.gatling.javaapi.http.*;
import requestBodies.CollectionRequestBodies;


import static io.gatling.javaapi.core.CoreDsl.*;
import static io.gatling.javaapi.http.HttpDsl.*;

public class VAPayment extends Simulation {

    private final ScenarioBuilder[] scnList = new ScenarioBuilder[5];

    private int users = 1;
    private HttpProtocolBuilder httpProtocol = http
            .baseUrl("https://lannister.uat.creditsaison.xyz")
            .contentTypeHeader("application/json")
            .authorizationHeader("Basic QGRNMU46UEAkJFcwckQ=");


    private void scnList() {
        CollectionRequestBodies vapayment = new CollectionRequestBodies();
       System.out.println(vapayment.VAPayment());

        for (int i = 0; i <= 4; i++) {

            scnList[i] = scenario("VA Payment " + users + "Users")
                    .exec(
                            http("VA Payment " + users + "Users")
                                    .post("/api/v1/axis/notification")
                                    .body(StringBody(vapayment.VAPayment())).asJson());
            users += 1;
        }
    }
    {
        scnList();
        setUp(
                scnList[0].injectOpen(rampUsers(5).during(3))
                        .andThen(
                                scnList[1].injectOpen(nothingFor(15), rampUsers(6).during(3))
                        )
                        .andThen(
                                scnList[2].injectOpen(nothingFor(15), rampUsers(7).during(3))
                        )
                        .andThen(
                                scnList[3].injectOpen(nothingFor(15), rampUsers(8).during(3))
                        )
                        .andThen(
                                scnList[4].injectOpen(nothingFor(15), rampUsers(9).during(3))
                        )



        ).protocols(httpProtocol);
    }
}```

So? What is your issue?

  • why you have a check that consider 500 as a failure? => Gatling HTTP protocol reference - checks
  • why you experience 500 status codes? => that’s for you to figure out, that’s a server side failure

Thanks @slandelle for mentioning the implicit checks that gatling does. Actually, we are getting unexpected 500 even though the API response is 200, will have to look at it again.
