What outcome occurs when the action within a flow does not return expected data?

When an action within a flow fails to return the expected data, the system is designed to handle such scenarios gracefully through the execution of an exception flow. This mechanism allows the application to manage errors or unexpected results without crashing, ensuring a smoother user experience.

By executing an exception flow, the application can define specific paths to take when something goes wrong, such as logging the error, notifying the user, or providing alternative actions. This approach improves the robustness of the application and helps in maintaining control over error management, rather than allowing the application to crash or yield unpredictable behavior.

In contrast to other potential outcomes, such as crashing or receiving a default response, the execution of an exception flow allows developers to implement customized error handling strategies that users may find more informative or helpful during an unexpected situation.
