WCF Service Call Queryrun

When the AX2012 method is called through the WCF service of AX2012, if the Queryrun object is called in the method, the error message is as follows:
System.ServiceModel.FaultException: Unable to cast object of type ' Dynamics.Ax.Application.QueryRun to type ' Dynamics.Ax.Application.SysQueryRun ". Server stack trace: in System.ServiceModel.Channels.ServiceChannel.HandleReply (Proxyoperationruntime operation, proxyrpc& RPC) in System.ServiceModel.Channels.ServiceChannel.Call (String action, Boolean OneWay, Proxyoperationruntime operation, object[] ins, object[] outs, TimeSpan timeout) in System.ServiceModel.Channels.ServiceChannelProxy.InvokeService (IMethodCallMessage Methodcall, Proxyoperationruntime operation) in System.ServiceModel.Channels.ServiceChannelProxy.Invoke (IMessage message) Exception rethrown at [0]: System.Runtime.Remoting.Proxies.RealProxy.HandleReturnMessage (IMessage reqmsg, IMessage RETMSG) in System.Runtime.Remoting.Proxies.RealProxy.PrivateInvoke (messagedata& msgdata, Int32 type)

Replace the Queryrun with its sub-class Sysqueryrun.

There should be something wrong in the middle of IL.
