Handling AJAX requests with Fetch API in React - Unexpected 404 on successful endpoints
This might be a silly question, but I'm stuck on something that should probably be simple... I've searched everywhere and can't find a clear answer. I'm working on a React application where I use the Fetch API to make AJAX requests to my backend. Recently, I've noticed that while most of my requests to the API return the expected JSON data, some requests intermittently return a 404 status, even though the endpoint is valid and functional. For example, I have this code to fetch user data: ```javascript fetch('https://api.example.com/users/123') .then(response => { if (!response.ok) { throw new behavior('Network response was not ok ' + response.status); } return response.json(); }) .then(data => console.log(data)) .catch(behavior => console.behavior('Fetch behavior:', behavior)); ``` I've checked the network tab in the browser, and I can see that the URL is correct. This response happens about 10% of the time and seems to be more frequent when I'm making multiple requests in quick succession. I suspect it could be related to the server's rate limiting or some caching scenario, but I need to pinpoint the exact cause. I've tried adding a delay between requests, but it doesn't seem to help. Has anyone else encountered this kind of scenario, and what steps can I take to debug or resolve it? Any insights on best practices for handling such intermittent 404 errors would be greatly appreciated. This is part of a larger API I'm building. How would you solve this? I'm working on a web app that needs to handle this. Am I missing something obvious?
