Subscriptions

Subscription Type throws an error when building for production.

Repro steps

yarn dev

Start a subscription:

subscription {
  hello
}

Publish an event:

query {
  hello
}

Observe that the subscription is pushed a payload.

Now that a subscription works with websockets, attempt to run a production build:

yarn build

Observe the following output:

yarn run v1.22.4
$ nexus build
