Explainer

When a Validation module operation finds data that breaks its rule, it throws a VALIDATION error instead of letting the flow carry on normally. Error mappings let you swap that error for a type that means more to your API. Error handlers (On Error Propagate and On Error Continue) then decide what happens next, such as returning a 404 with a clear reason phrase to the API caller.
Core information
  • A Validation module operation checks message data against one rule, such as Is Email or Is True. If the data fails the rule, the operation throws a VALIDATION error (a ValidationException), and the flow hands that error to its error handler.
More details and nuances
  • Many error types look reversed from the operation name, so match the thrown type, not the operation name. Is Null throws VALIDATION:NOT_NULL and Is Not Null throws VALIDATION:NULL. Is Blank String throws VALIDATION:NOT_BLANK_STRING and Is Not Blank String throws VALIDATION:BLANK_STRING. Is Empty Collection throws VALIDATION:NOT_EMPTY_COLLECTION and Is Not Empty Collection throws VALIDATION:EMPTY_COLLECTION. Is Elapsed throws VALIDATION:NOT_ELAPSED_TIME and Is Not Elapsed throws VALIDATION:ELAPSED_TIME.
