Data mismatch while exporting to JSON

[Jerome]

I used RIOT to migrate data from Elasticache to Memorystore. I ran my validation rules and everything succeeded. I then exported the data in Memorystore using file-export to a JSON file, flushed the DB and imported the JSON using dump-import.
Now when I run the validation program, the hashes do not pass validation since some of the binary objects seem to have changed.

I'm quite new to this so not sure if this is a bug or a platform dependent issue.
