An error occurred while retrieving the data through process model

Hi All,

 We are facing weird issue in production environment for one of the process model and same  process model is working in lower environments.

When we are calling query entity rule from process model with batch size lets say 25 then also it is giving us "An error occurred while retrieving the data" error.

if we run same rule independently in production then it is running successfully .

Same rule is working through process model with batch size 500 in lower environment . 

We have tried to reduce batch size also but no luck still getting same error in production . since rule is not failing independently we are not able to identify what could be the reason.

Has anyone run into the same problem?
