System.NullReferenceException：未将对象引用设置为对象的实例。而对象已经创建

Question

我知道该问题是由于未创建的对象或null，但我在所有设置后都遇到了问题。

我已经创建了该对象，该对象正在我的本地解决方案中工作，但是当我在共享服务器上部署它时，它会给我System.NullReferenceException: Object reference not set to an instance of an object.。

请提供帮助，代码如下

  TicketManagement objMyTicketDetails1 = new TicketManagement();
