Describe the bug
Deploying the attached BPMN diagram on SNAPSHOT and 0.21.1 throws an error.

Expected behavior
Workflow definition deploys.

The error is caused by an unknown extension zeebe:payloadMapping at the end event.

    <bpmn:endEvent id="EndEvent_0th2j52">
      <bpmn:extensionElements>
        <zeebe:payloadMappings>
          <zeebe:mapping source="sourceValue" target="targetValue" type="PUT" />
        </zeebe:payloadMappings>
      </bpmn:extensionElements>
      <bpmn:incoming>SequenceFlow_139z5p7</bpmn:incoming>
    </bpmn:endEvent>

It seems that the modeler creates an outdated extension element for the variable mappings.

However, we should improve the error message 😅

@saig0 @jwulf Hi. I got a similar error when trying to deploy a very simple bpmn. Did not have payloadMapping in my case.

@tvvignesh, this is not the same issue. In your example, the deployment is rejected because your BPMN is not valid. In the original case, an exception was thrown in the model API because of a bug.

As mentioned in the rejection failure message: the start event (id: "StartEvent_1") have a message event definition (i.e. it's a message start event) but it does not refer a message. In the Zeebe modeler, you need to select the message start event and select (or create) a message in the properties panel.

@saig0 Oops. You are right. Found the error and fixed it. Sorry for the confusion.
