Getting an Error for Invalid Subscription Requests

[Nuvindu]

I'm currently working on integrating GraphQL subscriptions in Ballerina language to a GraphiQL web based client. It uses websockets for subscriptions and works fine with valid subscription requests.
But for invalid subscription requests, an error occurs like this.

The GraphiQL client receives this websocket payload.

{"type":"error", "id":"b2dd2712-1ac5-48fa-9f25-8b88d3d80bf0", "payload":{"errors":[{"message":"Cannot query field \"messag\" on type \"MsgType\".", "locations":[{"line":4, "column":5}]}]}}

I removed errors field in the WebSocket payload and tried again.

{"type":"error", "id":"a2598b2a-ba44-4bee-be9a-40eea8e5cc4e", "payload":[{"message":"Cannot query field \"messag\" on type \"MsgType\".", "locations":[{"line":4, "column":5}]}]}

Then only the message field is correctly shown. But still an error occurrs.

In the console, the error is displayed as follows.

lib.ts:128 Uncaught (in promise) Error: Cannot query field "messag" on type "MsgType".

Thanks for reporting @Nuvindu! I thought this would be a regression with the recent refactorings we did, but seems like this has been an issue even before that. I opened a PR that would fix this.

@thomasheyenbrock Is there any update for this?

[thomasheyenbrock]

@Nuvindu thanks for following up! I have been busy the last weeks focussing on getting the new design ready, so this fell kinda off the plate 😞 I'll try to follow up this or next week 🤞

No worries!🙌. I saw the pr is almost completed. That's why I asked.
