Subscriptions Reference App not working out of the box

Hello Devs, hello Shopify team

I try to get the Subscriptions Reference App running, but the init fails.

I created an issue for this.

Also, the graphql-codegen doesn’t work out of the box.
Somebody else has reported this some weeks ago already.

Really would like to dive into this, but it’s hard this way.

Thanks for having a look.
