Shopify Koa missing HOST header

Shopify Koa missing HOST header

2 0 0

I am trying to generate an offline token with the shops using Shopify CLI for with Koa authentication module. 


Something like this: 


server.keys = [Shopify.Context.API_SECRET_KEY];
      accessMode: "offline",
      async afterAuth(ctx) {
        // Access token and shop available in ctx.state.shopify
        const { shop, accessToken, scope } = ctx.state.shopify;



However, when I try to run this flow with newly created stores, I am getting an error from the Shopify App Bridge, that Host is required, and app fails to render. 


class MyApp extends App {
  render() {
    const { Component, pageProps, host, isValidStore } = this.props;

    return (
      <AppProvider i18n={translations}>
            apiKey: API_KEY,
            host: host,
            forceRedirect: true,



I am fetching this using following method: 


MyApp.getInitialProps = async ({ ctx }) => {
  return { host: };



It is not able to get the host in the query parameter, probably because Shopify is not passing it. Is there something that I'm missing? 



Package versions are as followed: 


"@shopify/app-bridge-react": "2.0.13",
"@shopify/app-bridge-utils": "2.0.13",
"@shopify/koa-shopify-auth": "5.0.3",
"@shopify/polaris": "9.0.0",



Thank you for the help in advance.

Hi @Katarina_Heady. Thanks for reporting this. I'm a PM at Shopify. We've fixed this issue and the host parameter is now included.
