Could not find result for specified run id

Question

I use QMC QlikView to update documents. When I call the TriggerTask method, it successfully creates the task execution identifier. But with the same task execution identifier, when I click the GetEDXTaskStatus method to get the status the first 2-3 times, it says “Run”, but after a while it gives an error like: -

System.Exception: could not find a result for the specified execution ID "XXX"

Stack Trace: -

in System.ServiceModel.Channels.ServiceChannel.HandleReply (ProxyOperationRuntime operations, ProxyRpc & rpc) with System.ServiceModel.Channels.ServiceChannel.Call (String action, Boolean oneway, operation ProxyOperationRuntime, Object [] ins-Object, [] TimeSpan) in System.ServiceModel.Channels.ServiceChannelProxy.InvokeService (IMethodCallMessage method Call, ProxyOperationRuntime) with System.ServiceModel.Channels.ServiceChannelProxy.Invoke (iMessage message)

Please let me know if anyone has encountered this problem before.
