What occurs when an error is not handled in a Mule flow?

When an error is not handled in a Mule flow, the error is logged and flow processing stops. This is a critical behavior in Mule applications, as it ensures that unhandled exceptions do not go unnoticed, allowing for proper debugging and accountability.

When an error occurs, Mule automatically logs details about the error, which can help developers understand what went wrong and take corrective actions. Stopping the flow's processing at the point of error prevents further unintended consequences or data inconsistencies that could arise from continuing execution despite the fault.

Additionally, this error handling mechanism emphasizes the importance of implementing proper error handling strategies within the flows, such as using try-catch scopes or global error handlers, to manage exceptions gracefully and ensure that applications remain robust and reliable.
