[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:

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.

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

const event = `databases.chat.collections.users.documents.${userDocId}`;
return client.subscribe(event, callback);

Awesome gotcha! Thanks @Binyamin 😄
