condition in TransactWrite does not work

[shahjaidev]

I believe TransactWrite does not pass the condition corectly onto the AWS API on calling .save(condition= ...), tested multiple times and condition does not work.

gsi1pk_path = Path('GSI1PK')
save_condition = NotExists(gsi1pk_path)

    try:
        with TransactWrite(connection=Connection()) as transaction:
            transaction.save(lead, condition= save_condition)
            transaction.save(scheduled_message)
            transaction.save(conversation)
        print("Transaction completed successfully with phone_no_org_id composity key condition check")
        logger.info("Transaction completed successfully with phone_no_org_id composity key condition check")
    except TransactWriteError as e:
        logger.error("Transaction failed possible due to TransactWrite condition check. Error: %s", e.cause.response['Error']['Message'])
