Expecting ProcessInstance

BPMN & Modeling Discussion & Questions

Hello, I am trying to check a form input (created in the tasklist) with a java class, before passing the values further into a gateway to check if one of the values(userid) is given or not.

package com.camunda.supportGroup17.ServiceTasks;

import java.util.logging.Logger;

import org.camunda.bpm.client.ExternalTaskClient;

public class AnfragePrüfen {
	
	private final static Logger LOGGER = Logger.getLogger(AnfragePrüfen.class.getName());

	  public static void main(String[] args) {
	    ExternalTaskClient client = ExternalTaskClient.create()
	        .baseUrl("http://localhost:8080/engine-rest")
	        .asyncResponseTimeout(10000) // long polling timeout
	        .build();

	    // subscribe to an external task topic as specified in the process
	    client.subscribe("anfrage-prüfen")
	        .lockDuration(1000) // the default lock duration is 20 seconds, but you can override this
	        .handler((externalTask, externalTaskService) -> {
	          // Put your business logic here

	          // Get a process variable
	          String anfrage = (String) externalTask.getVariable("anfrage");
	          String email = (String) externalTask.getVariable("email");
	          String name = (String) externalTask.getVariable("name");
	          Long userid = (Long) externalTask.getVariable("userid");

	          LOGGER.info("Query has been created with information: '" + anfrage + "'user info: '" + email +" "+ name +"' and user ID: "+ userid);


	          // Complete the task
	          externalTaskService.complete(externalTask);
	        })
	        .open();
	  }

}

Error msg:

java.lang.AssertionError: Expecting ProcessInstance {id=‘4’, processDefinitionId=‘ServiceTasks:1:3’, businessKey=‘null’} to be ended, but it is not!. (Please make sure you have set the history service of the engine to at least ‘activity’ or a higher level before making use of this assertion!)

What am I doing wrong?
