Not able to get the ProcessEngine Instance

My Code is:

@Bean
public ProcessEngine processEngine() {
ProcessEngine processEngine = ProcessEngineConfiguration.createStandaloneProcessEngineConfiguration()
					  .setDataSource(environmentManager.getDataSource())
					  .buildProcessEngine();
			return processEngine;
}

I am getting this error:
