Unable to get property 'client' of undefined in SignalR

问题

I'm getting the error Unable to get property 'client' of undefined while accessing the hub method clientside. My code is as below:

 I have my hub like this:
    [HubName("command")]
    public class CommandHub : Hub
    {
        public void TrackStatusCommand(string serialNumber)
        {
            Groups.Add(Context.ConnectionId, serialNumber);
        }
        public void StatusCompleted(string serialNumber, bool status)
        {
            Clients.Group(serialNumber).statusCompleted(serialNumber, status);
        }
    }

    var hubProxy = $.connection.command, intervalHandle, timeout;
    $.connection.hub.logging = true;
    var priority = 0;
    var accNumber = $("#spnAccountNumber").data("templatepath");
    var model = $('#Model').text();
    hubProxy.client.statusCompleted = function (serialNumber, status) {
        $("#StatusData").css("display", "block");
        $('#StatusButton').prop('disabled', false);
        $.connection.hub.stop();
    };
    $.connection.hub.start({ transport: 'longPolling' }).done(function () {
        if ($.connection.hub.transport.name === "longPolling") {
            intervalHandle = setInterval(function () {
                statusCompleted(accNumber, model, priority, status);
            }, 30000);
        }
        hubProxy.server.trackStatusCommand(serialNumber);
        timeout = setTimeout(function () {
            $.connection.hub.stop();
            $("#StatusData").css("display", "block");
        }, 60000);
    }).fail(function () {
        $('#StatusButton').prop('disabled', false);
    });
    $.connection.hub.disconnected(function () {
        clearInterval(intervalHandle);
        clearTimeout(timeout);
    });

Once after deleting the temporary files from the root folder in the following path I'm not getting the error and it is working as expected.

C:\Windows\Microsoft.NET\Framework\v4.0.30319\Temporary ASP.NET Files

Please help. Thank you.
