estoy tratando de usar un proxy en mi paquete. json se llena así

 { "name": "type-redux-toolkit", "version": "0.1.0", "private": true, "dependencies": { "@material-ui/core": "^4.12.4", "@material-ui/icons": "^4.11.3", "@testing-library/jest-dom": "^5.16.4", "@testing-library/react": "^13.3.0", "@testing-library/user-event": "^13.5.0", "@types/jest": "^27.5.2", "axios": "^0.27.2", "react": "^18.2.0", "react-dom": "^18.2.0", "react-query": "^3.39.1", "react-router-dom": "^6.3.0", "react-scripts": "5.0.1", "styled-components": "^5.3.5", "web-vitals": "^2.1.4" }, "scripts": { "start": "react-scripts start", "build": "react-scripts build", "test": "react-scripts test", "eject": "react-scripts eject" }, "eslintConfig": { "extends": [ "react-app", "react-app/jest" ] }, "browserslist": { "production": [ ">0.2%", "not dead", "not op_mini all" ], "development": [ "last 1 chrome version", "last 1 firefox version", "last 1 safari version" ] }, "proxy": "http://localhost:8800/api/v1" //proxy is here }

y luego hacer una solicitud de publicación usando axios como este

 const res = await axios.post("/auth/login", credentials); console.log(res);

ahora, si solo pongo la URL completa en la solicitud, funciona, pero quiero usar el proxy.

eliminé el archivo package-lock.json y la carpeta node_modules y reinicié la aplicación como dicen algunas personas, pero nada
