Error on mapper only While Executing Pipeline

Question

I have this Pipeline which is working as expected without throwing any errors.All the Variables of this Mapper have been verified and is resolved into correct values

But on executing the same pipeline,this mapper is giving error

I have checked all Possibilities, but couldn’t find any solutions
Error reason:
original was not found while evaluating the expression:
$original.original.original

One possible reason:
On validation the pipeline will work only with the selected number of documents(Designer → User Settings):

On execution mode,  pipeline will work with all documents that are coming from the source. And you have successful run only with that data set(selected number of data on validation, not all the data).
So you must ensure that the logic within the snaps covering all the possible data scenarios.
