Getting exception while implementing delayed learning with abstract source and abstract destination

I have a requirement to store the user response for couple more manual approval process in the workflow before its updated to pxAdaptiveAnalytics.

I tried using Make Decision and Store Data For Later Response Capture for 10 mins in the Request Strategy with abstract data source and the destination.The adaptive model outputs are stored in pagelist and displayed in screen for user to select the offer manually.

When i execute the data flow i receive the following exception and pxDecisionResults dataset is not updated.

It seems the exception is because of pyLiveValue is not being set in DATA-DECISION-RESULTS!PXPRESERVEORIGINALRANK datatransform called from pxDelayedLearningFlow.

I am stuck here.Any help is appreciated?

The request and response dataflow works fine with abstract sources and finally updating the pxAdaptiveAnalytics in response dataflow though without delayed Learning
