I can confirm that I can get data from http://localhost:5000/api/products, but in the project, the request returns a 426 error. I tried requesting other APIs and can get data, or if I directly use axios.get('http://localhost:5000/api/products'), I can also get data. However, when I configure the proxy and request /api/products, I encounter the 426 problem. How can I solve this? It has been bothering me for a long time, and I can’t figure it out.
