Unable to Save data in data store while executing a process

Hi team,

I am facing an issue where My data is not getting saved in data store.

I am using a process model which can be seen below-

I have set up the process variable 'Result' for tracking the integration result.

Also, in the 3rd node,i.e., Write To Data Store Entities, I have used the following setup,

But Somehow data is not able to get stored in Data Store. To track the output of the write To Data Store Entity node, I have used an output variable,

Now see the below Screenshots while process was in Execution, the process variable details

I can see the storedValues is returning empty. 

What's the wrong with the above process ? 

Please help in this regard.
