where is the react project created with cra scaffolding? where is bundle.js?
 
 
react runs on port 3000 by default, and there is no error above when it runs directly. However, because it needs to cross domains, a reverse proxy is set up with nginx, and the above error occurs. The nginx.conf configuration is as follows:
   server {
        listen       3001;
        server_name  localhost;
 
        location / {
            proxy_pass http://localhost:3000;
        }
        location /api { 
            proxy_pass  http://192.168.33.3:8080;    
        }  
        location ~ \.(htm|html|js|css|jpg|png|gif|eot|svg|ttf|woff|woff2)$ {  
            root    html;     
        }    
                
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }
so, what"s the problem and how should it be set up?
