      I want to start a new process instance without providing variables.

      I do a POST at process-definition/key/interactive-lab-collector/start without body. This yields in an exception:

      java.lang.NullPointerException: null
	at org.camunda.bpm.engine.rest.sub.repository.impl.ProcessDefinitionResourceImpl.startProcessInstanceAtActivities(ProcessDefinitionResourceImpl.java:140) ~[camunda-engine-rest-core-7.7.0-alpha1.jar:7.7.0-alpha1]

      So you have to provide a body with an empty JSON object:

      {}

      I stumble over that very regularly. It would be nicer for the user to allow that empty body as non-experienced people might not guess what the problem exactly is.

        This is the controller panel for Smart Panels app
