Subscriptions in Graphiql

[ppbpdx]

I am upgrading my app to the latest version using the FastApi example.

Previously I mounted the subscriptions handler like this:

app.mount("/ws", GraphQL(subscription_schema, debug=True))

And if I pointed a browser to localhost/ws the graphiql interface let me test out and experiment with the subscriptions. This was very useful to debug and document the subscriptions.

In the new documentation example I am mounting my subscriptions like this:

@app.websocket("/api")
async def graphql_subscriptions(
    websocket: WebSocket,
    db = Depends(get_db),
):
    # Expose database connection to the GraphQL through request's scope
    websocket.scope["db"] = db
    await graphql_app.handle_websocket(websocket)

However when I try to test a subscription through graphiql I get an error:

"message": "Your GraphiQL createFetcher is not properly configured for websocket subscriptions yet. Please provide subscriptionUrl, wsClient or legacyClient option first.",

Is there a good way to enable testing subscriptions through graphiql that anyone can recommend? Is this something I need to configure in the client code?

Thanks for the help!
