Research direction
Review the linked PR #759 discussion (comment r571172737) for context. Examine how set404Handler, setErrorHandler, and setApiSpec currently handle function arguments. Propose and implement a validation mechanism (e.g., checking argument names and types) for these functions, and consider extending to other customizable behaviors.
