  Incorrect configuration of the process chain.
  A missing or incorrectly defined event or node.
  Logical errors in the sequence of events and nodes.
  
  
  
  Event Configuration Issues: The events defined in the process chain may not be properly linked or configured, leading to invalid transitions.
