dyno failing to restore incremental backup?

simple test case with a small table:

ENV=dev
TABLE=dsrtest2

. config.env.$ENV

bin/incremental-backfill.js $AWS_REGION/$TABLE s3://$BackupBucket/$BackupPrefix

bin/incremental-snapshot.js s3://$BackupBucket/$BackupPrefix/$TABLE  s3://$BackupBucket/${TABLE}-snapshot

s3print s3://$BackupBucket/${TABLE}-snapshot | dyno put $AWS_REGION/dsr-test-restore-$TABLE

%% sh test-backup.sh

Next step would be to diff the two tables - but the pipe to dyno fails. I've tried 1.0.0 and 1.3.0 with the same result.

What data format is dyno expecting? The file on s3 (tried multiple tables including real data tables) is a binary blob?

So maybe this is a problem with backfill? or I'm missing something? :)

Riproduci la pipeline descritta nell'issue con bin/incremental-backfill.js, bin/incremental-snapshot.js e s3print. Leggi node_modules/dyno/lib/serialization.js e node_modules/dyno/bin/cli.js nel punto in cui si verifica l'errore di parsing del JSON, quindi confronta l'output dello snapshot con il formato di input previsto da dyno. Il lavoro è completato quando lo snapshot generato può essere passato correttamente a dyno put e la tabella ripristinata può essere confrontata con quella di origine.
