Uncaught TypeError: signalR.httpConnection is not a constructor

Question

I am trying to get all connected users with Identity but it says the error as title which is : Uncaught TypeError: signalR.httpConnection is not a constructor

For this line :

let hubUrl = '/chatHub'
let httpConnection = new signalR.httpConnection(hubUrl);
let hubConnection = new signalR.hubConnection(httpConnection);

hubConnection.on('SetUsersOnline', usersOnline => {
    if (usersOnline.length > 0) {
        $('#onlineUsers').innerText = '';
        $.each(usersOnline, function (i, user) {

            addUserOnline(user);

        });

    }

});

hubConnection.start();

Syntax for SignalR was changed quite often and it's hard to tell what is and isn't correct for what version. Just update to latest SignalR and try this:

const connection = new signalR.HubConnectionBuilder()
                    .withUrl("/chatHub")
                    .configureLogging(signalR.LogLevel.Information)
                    .build();

connection.on('SetUsersOnline', usersOnline => {
    if (usersOnline.length > 0) {
        $('#onlineUsers').innerText = '';
        $.each(usersOnline, function (i, user) {
            addUserOnline(user);
        });
    }
});

connection.start().catch(err => console.error(err.toString()));
