Client side error on Autentication failure?

[skatoch27]

Given this:

function onAuthorizeFail(data, message, error, accept){ 
    console.log('failed connection to socket.io:', message);
    if(error)
    accept(new Error(message));
}

How to handle this on the client side?

The documentation mentions:

// If you use socket.io@1.X the callback looks different
// If you don't want to accept the connection
  if(error)
    accept(new Error(message));
  **// this error will be sent to the user as a special error-package
  // see: http://socket.io/docs/client-api/#socket > error-object**

But its not clear what to do on the client side. For example none of the following are triggered:

    socket.on('error',function(data) {
        console.log('error...',data);
    });
    
    socket.on('connect_error',function(data) {
       console.log('connect error...',data);
    });

Updating upon further tests, onAuthorizeFail gets called with error==false.

So removing the if(error) condition triggers "packet" (not connect_error) event:

function onAuthorizeFail(data, message, error, accept){ 
    console.log('failed connection to socket.io:', message);
    accept(new Error(message));
}

So what is the purpose of "error"?

Edit: packet is triggered instead of connect_error
