Request["InnerErr"] is null. you can't call ToString method of null object. it will throw NullReferenceException

you can check null and then call to string method like below

C#

if(Request["Err"]!=null)
  Label_ErrorFrom.Text = Request["Err"].ToString();
if(Request["InnerErr"]!=null)
  Label_ErrorMessage.Text = Request["InnerErr"].ToString();

OR

C#

protected void Page_Load(object sender, EventArgs e)
{
    Label_ErrorFrom.Text = Request["Err"] as string;
    Label_ErrorMessage.Text = Request["InnerErr"] as string;
}
