reactjs - React CRA proxy issue

Question

I put the line 'proxy': 'http://192.168.1.36:4000' which corresponds to the IP address and the port of my expressjs API but when I perform a fetch to retrieve information on my server I get an error like:> POST http: // localhost: 3000 / api / users / login 400 (Bad Request). From what I understood from the error, the fetch uses the port of my react app and not that of my express API. Port 3000 is not my API's.

{
  "name": "portfolio",
  "version": "1.0.0",
  "private": true,
  "proxy": "http://192.168.1.36:4000", // This line
  "dependencies": {
    "@testing-library/jest-dom": "^4.2.4",
    "@testing-library/react": "^9.5.0",

  },
