Post request with ajax jquery reterns a 404 status

The error arises from attempting to POST data to an endpoint that only responds to GET requests. Ensure the server defines a POST route.

In Express, you can handle incoming POST requests using app.post. The current code does not define any POST route, leading to a 404 error.

To fix this, create a POST route in app.js by using app.post('/your-endpoint', (req, res) => { /* your logic here */ });.

Make sure to correctly specify application/json or application/x-www-form-urlencoded as the contentType in jQuery AJAX for proper request handling.
