jquery ajax error-handling JavaScript

I'm reviewing some code and I'm stuck trying to I can't seem to get I tried several approaches but none seem to work....... I'm working on a jQuery function that makes an AJAX call to fetch user data from an API endpoint. I've set up a custom error handler to deal with various HTTP response codes, but I'm having trouble specifically with 404 errors. In my current setup, when a 404 occurs, I expect my custom error message to be displayed, but instead, I receive the default browser error message. Here's the relevant code: ```javascript $.ajax({ url: 'https://example.com/api/users/' + userId, method: 'GET', dataType: 'json', success: function(data) { // Process the data }, error: function(xhr, status, error) { if (xhr.status === 404) { console.error('User not found.'); $('#error-message').text('User not found. Please check the ID.'); } else { console.error('An unexpected error occurred: ' + error); $('#error-message').text('An unexpected error occurred.'); } } }); ``` I've double-checked that the endpoint is correct and that the user ID is valid, but when the user ID does not exist, I still see the browser's default 404 page instead of my custom error message in the `#error-message` element. I've tried adding `preventDefault()` and checking the network tab in the Chrome DevTools, and I can confirm that the request is indeed returning a 404 status. Is there a way to ensure that my jQuery error handling captures the 404 error properly and avoids displaying the default browser error page? I'm using jQuery version 3.6.0, and I'm testing in Chrome version 96.0.4664.93. What am I doing wrong? Thanks in advance!
