MVC - Input string was not in a correct format - Application_Error - Global.asax

Question

I do not know where this exception is being thrown. I intercept the exception in Application_Error. Application_Error is called after the page is fully loaded. It occurs on any page.

Code of Application_Error:

protected void Application_Error(object sender, EventArgs e)
{
                string errorMessage = "";
                LogServices logServ = new LogServices();

                Exception exception = Server.GetLastError();
                string exMsg = exception.Message;
                Exception _ex = exception.InnerException;
                while(null != _ex)
                {
                    exMsg = string.Format("{0} {1}", exMsg, _ex.Message);
                    _ex = _ex.InnerException;
                }



                string logId = logServ.log(exception, "", Context.Request.UserAgent);

                if (exMsg.IndexOf("was not found") != -1)
                {
                    errorMessage = ElizeuSites.AssimEstaEscrito.Resources.Global.PageNotFound;
                    Server.ClearError();
                    string urlRedirect = String.Format("/FrontEnd/{0}/{1}?{2}={3}&errorMessage={4}", "Error", "PopUpError", "logId", logId, errorMessage);
                    Server.TransferRequest(urlRedirect);
                }
}

Captured with error Server.GetLastError():

"Input string was not in a correct format "

With the tip of Hakunamatata I saw that the problem was browserlink. In the MSDN blog(Link of blog) It has the full explanation of the browserlink. I could solve the problem with the configuration below.

  <appSettings>
    <add key="vs:EnableBrowserLink" value="false"/>
  </appSettings>
