Error:Network request failed

i am trying to use wrangler graphql server
My config file
import Constants from 'expo-constants';

// get the localhost ip address at runtime using the Expo manifest
// this enables both simulator and physical device debugging with our local api
let localhost;
if (Constants.manifest.debuggerHost) {
localhost = Constants.manifest.debuggerHost.split(':').shift();
}

// set environment variables
const ENV = {
dev: {
API_URI: http://127.0.0.1:8787/
},
prod: {
// update the API_URI value with your publicly deployed API address
API_URI: 'https://shop-on-wheel-server.veensiva10.workers.dev/'
}
};

const getEnvVars = (env = Constants.manifest.releaseChannel) => {
// DEV is set to true when react-native is running locally in dev mode
// DEV is set to false when our app is published
if (DEV) {
return ENV.dev;
} else if (env === 'prod') {
return ENV.prod;
}
};

export default getEnvVars;
