When should I use a Error End Event?

Use Error End Events when a process path should end abnormally-validation failures, integration errors, business rule violations. Error handlers can then implement recovery or notification logic.

How is the Error End Event different from related elements?

Error End Events throw errors that propagate up for handling; None End Events simply terminate. Escalation End Events raise attention without indicating failure; Errors indicate exceptional conditions.

Error End Event

An Error End Event terminates a process path by throwing a named error. The error propagates up to be caught by error boundary events or error start events in parent scopes.

What is an Error End Event?

An Error End Event terminates execution by throwing a named error. The error propagates upward through the process hierarchy until caught by an error handler (boundary event or event sub-process).

Visual Representation

The event shows a thick-bordered circle containing a filled lightning bolt. The thick border indicates End Event; lightning bolt represents error/exception.

Key Characteristics

Error propagation: Thrown errors bubble up until caught
Named errors: Specific error codes enable targeted handling
Interrupting: Catching an error typically interrupts current processing
Transaction rollback: Errors in transactions trigger compensation

Common Use Cases

Validation Failure

End the processing path with a "ValidationError" when business rules are violated.

Integration Failure

Throw "ServiceUnavailable" error when external service calls fail after retries.

Business Exception

End with "InsufficientFunds" error when payment cannot be completed.
