What mechanism does MuleSoft use for error handling in flows?

MuleSoft uses exception strategies as the primary mechanism for error handling in flows. Exception strategies provide a systematic way to manage errors that occur during the execution of a Mule application by allowing developers to define how specific types of exceptions should be handled.

These strategies can be configured at various levels, such as at the global level for the entire application or at the flow level for specific flows. When an error occurs, MuleSoft invokes the appropriate exception strategy based on the type of exception and the defined logic within those strategies. This can include actions such as logging the error, sending an alert, or performing a retry.

The flexibility of exception strategies also enables developers to customize error handling based on the needs of their application. For instance, they can use different strategies for different flows or even differentiate how to handle exceptions based on the source of the error.

While the other options may play roles in the broader context of application management and flow execution, they do not specifically highlight the structured mechanism that MuleSoft provides for centralized error handling, which is central to effective application development in MuleSoft.
