Row Hash validation with BQ - TypeError: Object of type bytes is not JSON serializable

[nehanene15]

Getting errors when running a row hash validation like so between BQ to BQ and Hive to BQ.
data-validation -v validate row -sc my_bq_conn -tc my_bq_conn -tbls pso-kokoro-resources.hivetest.mascot --hash '*' -pk id

The return value from the BQ sha256() function is a bytestring value that cannot be compared to the string return value from the Hive sha2() function. This also throws an error when outputting results to BigQuery result handler.
