Hi

I've used json file and converted into BPMN model, deploying and executing it.

it got deployed but it is giving NULL Pointer exception

ProcessDefinition processDefinition = repositoryService.createProcessDefinitionQuery()
                  .deploymentId(deploymentId).singleResult();

                processInstance = runtimeService.startProcessInstanceById(processDefinition.getId());


I ve attached the code and json.

Please help
