Where can you add an error handler in a Mule application?

In a Mule application, you can add an error handler in various contexts, making it versatile and aligned with the specific requirements of your integration flows. The correct choice allows for error handling within both a try scope and a regular flow, which means you can encapsulate actions that may throw errors specifically within the boundaries of the flow where they occur.

The try scope is particularly useful as it allows you to manage errors that might arise from the activities within its block, enabling you to define localized error handling strategies. This means you can specify alternate processing paths or corrective actions that should occur right where the error happens, providing a granular control over error handling.

In a regular flow, you can implement error handling strategies to catch exceptions thrown by any component. This capability ensures that you can manage errors proactively, log them, or reroute the flow in response to exceptions under the control of the flow’s configuration.

By integrating error handling into both try scopes and regular flows, users can create more robust applications that can gracefully manage runtime issues without affecting the entire application negatively. This flexibility allows developers to design solutions that are resilient and tailored to specific operational scenarios.

The other options are limited in scope and do not reflect the full capabilities of error handling in Mule applications.
