What should you define to capture fail situations detected by return values?

To capture fail situations detected by return values, defining a request attribute is essential. Request attributes allow you to specify additional context about the requests and responses that your application handles. When a return value indicates a failure, this attribute can capture relevant information that assists in diagnosing the issue.

By utilizing request attributes, you can classify and identify specific conditions under which failures occur. This aids in setting up better monitoring and alerting mechanisms in your application, improving your ability to respond to issues proactively.

In contrast, while response handling rules are important for managing how responses are processed, they do not specifically capture failure return values. Error codes may indicate a failure, but they typically require a corresponding response handling rule or request attribute to fully utilize the data effectively. System alerts generally serve as notifications for issues but are more reactive rather than focused on the detailed capturing of data related to return values, which is where request attributes excel.
