Uncaught Error for declining connection initialization at "OnNameSpaceconnect"

Hi,

I'm declingin the initialiation the connection of the websocket to a namespace as follows:

var serverEvents = websocket.Namespaces{
	namespace: websocket.Events{
		websocket.OnNamespaceConnect: func(nsConn *websocket.NSConn, msg websocket.Message) error {
			return fmt.Errorf("No role 'admin'")
		},
		websocket.OnNamespaceConnected: [...]

At the client side the connection initialization is from the examples as follows:

async function runExample() {
        try {
          const conn = await neffos.dial(
            wsURL,
            {
              default: {
                // "default" namespace.
                _OnNamespaceConnect: function(nsConn, msg) {
                  console.log(nsConn);
                  console.log(msg);
                },
                _OnNamespaceConnected: function(nsConn, msg) {
                  addMessage("connected to namespace: " + msg.Namespace);
                  handleNamespaceConnectedConn(nsConn);
                },
                _OnNamespaceDisconnect: [...]

The error from the js library is as follows:

Uncaught (in promise) Error: No role 'admin'
at deserializeMessage (neffos.min.js:1)
at a.handleMessage (neffos.min.js:1)
at a.handle (neffos.min.js:1)
at WebSocket.i.onmessage (neffos.min.js:1)

My use case is that I want only allow specific users the connection to a websocket namespace. On the client side the returned error should be caught and sent to the end user properly.

Did I cancel the initialization of the websocket connection to the namespace in the correct way?

Start by tracing deserializeMessage and handleMessage in neffos.min.js, then compare the namespace connection error path with the client callbacks shown in the issue. Done means a rejected namespace initialization can be handled by the client without an uncaught promise error, while preserving the server's "No role 'admin'" message.
