How can I prevent 'status_in_page_errors' from occurring?

Implement robust error handling in both client-side (JavaScript) and server-side code. Ensure that server-side code returns appropriate HTTP status codes for different error conditions (e.g., 404, 500, 400). Use try-catch blocks to handle potential exceptions and avoid exposing stack traces to the user. Implement comprehensive input validation and sanitization to prevent invalid data from causing errors. Implement proper logging and monitoring to identify and address errors quickly. Use server-side validation to check the integrity and existence of data before rendering it in HTML.
