Missing Handler

Missing handlers leave your application vulnerable to crashes and unpredictable behavior. When an error is thrown and there's no specific code to catch and manage it, the program can't gracefully recover or decide how to proceed, often leading to a complete termination or exposing internal details. To prevent this, developers should implement structured exception handling around risky operations. This means anticipating potential points of failure—like network calls, file operations, or data parsing—and defining clear, secure responses for each scenario to maintain application stability and security.
