Subscriptions are sent to HTTPS endpoint and behave like queries

This issue pertains to the following package(s):

• GraphQL Playground - Electron App

What OS and OS version are you experiencing the issue(s) on?

Mac OS X Sierra

What version of graphql-playground(-electron/-middleware) are you experiencing the issue(s) on?

1.5.4.

What is the expected behavior?

Running a subscription sets up an active WS connection that listes to events. Whenever an event is fired, the Playground shows the related data according to the subscription query.

What is the actual behavior?

Running a subscription sends a HTTPS request, which gets an immediate response. No active listening happens.

What steps may we take to reproduce the behavior?

prisma init test
cd test
prisma deploy
prisma playground

subscription {
  user(where: {
    mutation_in: [CREATED, UPDATED, DELETED]
  }) {
    mutation
    node {
      id
      name
    }
    updatedFields
    previousValues {
      id
    }
  }
}

Thanks for reporting this Nilan! As a temporary workaround, I’ve found that it often helps to start a subscription on the database layer (which seems to work reliably). So, e.g. for a Post model, it could look like this:

subscription {
  post {
    node {
      id
      title
    }
  }
}

upgraded to "graphql-yoga": "^1.14.10", then ran yarn dev to start the playground again. Still getting the null subscription data though and the playground settings from cog wheel still look like my reference above.

Not the end of the world, the work around is works for me. I don’t want you to have to spin your wheels helping me get it up to speed. 😃
