Validation Error org.camunda.bpm.engine.impl.bpmn.parser.BpmnParse.execute(BpmnParse.java:271)

Hi,
I have a Bpmn process and I have used a standalone Camunda Modeler v.3.1.0 to write my process.
I haven’t error in the Modeler and in Eclipse project.
I have validated the bpmn diagram with a simple java method:

            BpmnParser parser = new BpmnParser();
	        BpmnModelInstance modelinstance =  Bpmn.readModelFromStream(getClass().getClassLoader().getResourceAsStream("titolo_ii_istrutturia.bpmn"));
	        parser.validateModel(modelinstance.getDocument());

and Unit test

@Test
  @Deployment(resources = {"titolo_ii_istrutturia.bpmn"})
  public void shouldExecuteProcess() {
    // Given we create a new process instance
    ProcessInstance processInstance = runtimeService().startProcessInstanceByKey("istruttoria_id");
    // Then it should be active
    assertThat(processInstance).isActive();
    // And it should be the only instance
    assertThat(processInstanceQuery().count()).isEqualTo(1);
    // And there should exist just a single task within that process instance
    assertThat(task(processInstance)).isNotNull();

    // When we complete that task
    complete(task(processInstance),withVariables("approvatore", "approvatore"));
    
 
    // Then the process instance should be ended
    assertThat(processInstance).isEnded();
  }

But, when I try to deploy my process in camunda-tomcat-7.10 I’ll get the following stack-trace:

How I can detect the right point where my bpmn diagram fails?
The " line 619 | column 38 " correspond a service task.

<bpmn:serviceTask id=“ServiceTask_0ykaplt” name=“Richiesta xx xxxxxxx” camunda:class=“xx.xx.xx.xxxx.xxx.LoggerDelegate”>
bpmn:incomingSequenceFlow_14rlta7</bpmn:incoming>
bpmn:outgoingSequenceFlow_0j0gjww</bpmn:outgoing>
</bpmn:serviceTask>

I don’t understand where is the error and where my diagram fails.
Thanks in advance for any suggestions or help.
Regards
Antonio

Do you have a message task or event that is not configured?

Hi Stephen,
at line 619 I have a service task with java implementation.
May I send you my bpmn file? But I can’t publish here my process.
Regards
Antonio

Dont look at the specific “line”. Review your BPMN file and look for a message event or anything that is generate a “message”. From the error you have a un-configured message

I have 2 pools.
In the first pool have a service task. From this task I send a message to the second pool.
This is a start event for the second pool.
The message is:
<bpmn:message id=“Message_0ex8hfl” name=“Message_RichiestaIntegrazione” />

The start event of second pool is

<bpmn:startEvent id=“StartEvent_0m22wyk”>
bpmn:outgoingSequenceFlow_0ny381c</bpmn:outgoing>
<bpmn:messageEventDefinition id=“MessageEventDefinition_1dvzz79” messageRef=“Message_0ex8hfl” />
</bpmn:startEvent>

what I m missing?

Thanks
Antonio

Past your bpmn into a github GIST or pastebin and share the bpmn please

https://pastebin.com/vY76uc5e

Can you paste in a github gist. unable to open pastebin currently

I have solved by using another open source bpmn modeler.

Hi Antonio,
I am also getting same issue, How u solved this issue,Can you please explain me,
Thanks in advanced.

Hi Ravi,
I have used imixs BPMN modeler (https://www.imixs.org/). It’s an eclipse based modeler and open source engine. Whit this modeler you can discover where your BPMN is not valid. In my case, I had a branch without the end element.
See :
<bpmn:intermediateCatchEvent id=“IntermediateCatchEvent_1hbria9” name=“controdeduzione non ricevuta”>
