Hello, I am trying to create my first camunda (using Java) project. After following a tutorial on youtube, I am always getting the following error with simpleDemo as the name of the project :
01:03:21.337 [main] ERROR org.camunda.bpm.engine.context - ENGINE-16004 Exception while closing command context: no processes deployed with key ‘SimpleDemo’: processDefinition is null
org.camunda.bpm.engine.exception.NullValueException: no processes deployed with key ‘SimpleDemo’: processDefinition is null
Could anyone provide some help please?
