Question. How to use it with helix graphql.

[blackpr]

Hello,
If this is not the place for this question please feel free to close/delete it.

So. I have a graphq-helix graphql server.
I can connect to subscriptions with the buil-in graphiql

subscription BasicSubscription {
  clock
}

I can connect with EventSource

const eventSource = new EventSource(u)
      const payload = await new Promise<any>((resolve) => {
        eventSource.addEventListener('message', (event: any) => {
          console.log(event.data) // <------- this logs the message
          resolve(event.data)
          eventSource.close()
        })
      })

But I cannot connect with this client nor apollo. I get the same error Error: Missing message event
Exampole code:

      const client = createClient({
        url: ''http://localhost:3000/graphql,
      })
      client.subscribe(
        { query: 'subscription {clock}' },
        {
          next: () => {
            console.log('yep')
          },
          error: (e) => {
            console.log('nope', e) <---- I get the error here
          },
          complete: () => {
            console.log('done')
          },
        }
      )

I would really appreciate any help

Thank you

Sadly, graphql-helix does not implement the GraphQL over Server-Sent Events Protocol that graphql-sse leverages; it uses its own protocol instead. Consider opening an issue over there.
