NGINX - Serving a create-react-app application on one port and my api on another port

There is problem with quotation in proxy_pass. It should looks like:
location / {
proxy_set_header X-Forwarded-For $remote_addr;
proxy_set_header Host $http_host;
proxy_pass http://127.0.0.1:5000;
}
location /api {
proxy_pass http://127.0.0.1:9000;
}
