ActionFlowPortTypeOnFailure Field

Invoked when a node has failed to complete its task because a third party service failed to respond with a success status.
This can be because of a timeout, a network error, a server error on their part or because our input is faulty.
Unlike "our" errors, which are unexpected and not acceptable, third party errors are expected and should be handled gracefully.
