Describe the Issue
When attempting to subscribe to a GraphQL subscription, the handshake is successful but the websocket is disconnected on the first keep-alive message.
When subscribing in GraphQL Playground (which works fine), you can see that the keep-alive messages ({"type":"ka"}) occur regularly:
But it seems the Postman GraphQL Client doesn't know how to handle them.
The subscription is being served by a graphql-java server using the graphql-ws protocol.
Steps To Reproduce
- Attempt to start a subscription
- See the subscription fail
