[Solved] WebSocket is closed before the connection is established?

I'm receiving this error when attempting to setup a realtime connection listening for updates to a specific document in my users connection.

My code is as follows:

TypeScript

export async function addUserUpdateListener(auth_id: string, callback: (payload: RealtimeResponseEvent<unknown>) => void) {
  try {
    const userData = await db.listDocuments(
      'chat',
      'users',
      [
        // @ts-ignore
        q.equal('auth_id', [auth_id])
      ]
    );
  
    if (userData.documents.length > 0) {
      const [user] = userData.documents;
      const {$id: userDocId} = user;
      const event = `databases.chat.collections.users.documents.${userDocId}.update`;
      return client.subscribe(event, callback);
    }
  }
  catch (e) {
    console.warn(e);
  }

  return null;
}

And the path it's attempting to open a websocket connection to is: wss://cloud.appwrite.io/v1/realtime?project=648a2161cc4d4565adc2&channels%5B%5D=databases.chat.collections.messages.documents&channels%5B%5D=databases.chat.collections.users.documents.648a2228362b7d35edd2.update

Note it appears to be amalgamating the two realtime listeners I have, but I assume this is how it's meant to function.

TL;DR

The user is experiencing an error where the WebSocket connection is closing before it is established while trying to setup a realtime connection listening for updates to a specific document. The code provided subscribes to a specific event using the user's document ID, but it seems that the URL for the WebSocket connection is combining multiple realtime listeners. The user's code is written in TypeScript. A possible solution is to subscribe to the channel that includes the "update" event using the specific event format mentioned in the support thread.

It's also worth noting that the other realtime listener I have setup is still working.

Channels are a bit different from events, https://appwrite.io/docs/realtime#channels To subscribe to channel that includes the update event you need to do something like this
