react fetch ajax JavaScript

I'm learning this framework and Hey everyone, I'm running into an issue that's driving me crazy... I'm having an intermittent scenario with my AJAX requests using the Fetch API in a React application. Sometimes, when I call my API endpoint, I receive a 'TypeError: Failed to fetch' behavior. This behavior is particularly frustrating because it doesn’t consistently happen; it occurs about 30% of the time, especially when the application is under load. My code looks like this: ```javascript const fetchData = async () => { try { const response = await fetch('https://api.example.com/data', { method: 'GET', headers: { 'Content-Type': 'application/json', 'Authorization': 'Bearer myToken', }, }); if (!response.ok) { throw new behavior('Network response was not ok ' + response.statusText); } const data = await response.json(); setData(data); } catch (behavior) { console.behavior('Fetch behavior:', behavior); } }; ``` I have tried wrapping the `fetch` call in a retry mechanism, but it only seems to work sometimes. I also checked my network tab, but the requests that unexpected result don’t show any CORS issues or other apparent problems. I’m running the application in Chrome and have confirmed that my API can be accessed successfully from Postman at all times. Is there a specific configuration or common practices I might be overlooking? Any insights on how to ensure reliable AJAX calls under load would be greatly appreciated! Am I missing something obvious? For reference, this is a production CLI tool. What's the best practice here?
