Visualize.js authentication error after second login

I have a website—utilizing Visualize.js—that has a simple login/logout feature. Everytime I login I call

the authenticateUser() and logout destroySession() method. When I try login and then logout and then login again, when I

try to render my existing reports I get this thrown error:

The functions authenicateUser() and destroySession() are shown below:

function authenticateUser () {
    var myConfig = {
        auth : {
            name     : "superuser",
            password : "superuser"
        }
    };
    visualize.config( myConfig );
}
 
function destroySession() {
    visualize( function ( v ) {
        // Logout form JRS and finish the session.
        v.logout().done( function () {
        } );
    } )
}

I would like to point out that when I first login my account this error is not thrown and renders the reports perfectly.

Why is this happening after logout and then login again?
