Anyone know the most common js fetch failed reason and how to fix it?

Yo! Been there, done that. The js fetch failed reason is often headers or CORS, but don’t forget about network issues or even browser caching.

Try adding `{ cache: 'no-store' }` to your fetch options. And double-check your headers—like, make sure you’re sending `Content-Type: application/json` if needed.

If you’re still stuck, check out this tool called Requestly. It lets you modify headers and debug CORS issues super easily.
