How can I debug a 500 error received through Axios?

Debugging a 500 error requires looking at the server-side logs. Axios only tells you *that* an error occurred, not *why*. Check your server's error logs (e.g., Apache, Nginx, Node.js console) for detailed error messages, stack traces, and any clues about the cause. Also, examine the request data sent by Axios to ensure it's in the expected format. Using a network inspector in your browser's developer tools can help verify the request.
