Getting 'Method Not Allowed 405' Error – How Do I Fix This? or Why Am I Seeing a 'Method Not Allowed

Hey! Had this exact issue yesterday.

For me, it was a dumb mistake—I was using PUT in the frontend but the backend only accepted POST.

DevTools network tab helped me spot it. Look for the "Request Method" in the headers.

If you’re using fetch/Axios, triple-check the method parameter!
