enter image description here Why can't I connect to the backend? I hope someone can help me The error '404 (Not Found)' occurs when a POST request to http://localhost:3000/products is not processed by the server because the corresponding route is not found on the server. This typically happens when the server does not have a POST route for '/products' defined or there is a mismatch in the definition of this route. Please double-check your server-side code to ensure that the POST route '/products' is defined correctly and activated. Make sure that you have added this route using the POST method in your server code, and the server is running on port 3000.
