How to have a flexible Step description for a custom Task

[Mo0rBy]

I've created a custom Task for a REST API interaction. In one instance, I want to send the request with a pathParameter (of the processInstanceId) only and in another instance, I want to send the request with the pathParameter (of the processInstanceId) as well as 2 query parameters (firstResult and maxResults). Now because I have these 2 slightly different situations, I want to be able to modify the value of the @Step annotation so that I don't see this in my report:

Below you can see my custom Task code and notice the stepString class attribute. I hoped that this solution would allow me to have a flexible @Step annotation, depending on which method (withId() or withIdAndQueryParams()) was called, but I get the error The value for annotation attribute Step.value must be a constant expression. Is there any way that I can modify the Step value depending on which method is called?

public class GetSubtasksForProcessInstance implements Task {

    private static final String SERVICE_BASEURL = {myServiceBaseUrl}

    private final String processInstanceid;
    private final String firstResult;
    private final String maxResults;
    private final String stepString;

    public GetSubtasksForProcessInstance(String processInstanceid) {
        this.processInstanceid = processInstanceid;
        this.firstResult = null;
        this.maxResults = null;
        this.stepString = "{0} fetches the Subtasks associated with the process instance with id: #processInstanceid";
    }

    public static GetSubtasksForProcessInstance withId(String processInstanceid) {
        return instrumented(GetSubtasksForProcessInstance.class, processInstanceid);
    }

    public GetSubtasksForProcessInstance(String processInstanceid, String firstResult, String maxResults) {
        this.processInstanceid = processInstanceid;
        this.firstResult = firstResult;
        this.maxResults = maxResults;
        this.stepString = "{0} fetches the Subtasks associated with the process instance with id:#processInstanceid and query parameters firstResult:#firstResult and maxResults:#maxResults";
    }

    public static GetSubtasksForProcessInstance withIdAndQueryParams(String processInstanceid, String firstResult, String maxResults) {
        return instrumented(GetSubtasksForProcessInstance.class, processInstanceid, firstResult, maxResults);
    }

    @Override
    @Step(this.stepString)
    public <T extends Actor> void performAs(T actor) {
        actor.can(CallAnApi.at(SERVICE_BASEURL));
        if ((firstResult == null) && (maxResults == null)) {
            actor.attemptsTo(
                Get.resource("/{processInstanceId}/subtasks")
                    .with(request -> request
                        .pathParam("processInstanceId", processInstanceid)));
        } else {
            actor.attemptsTo(
                Get.resource("/{processInstanceId}/subtasks")
                    .with(request -> request
                        .pathParam("processInstanceId", processInstanceid)
                        .queryParam("firstResult", firstResult)
                        .queryParam("maxResults", maxResults)));
        }
    }
}

just use @Step("#stepString")

@ricardorlg Oh wow thanks! I really missed the obvious there.
