Airbyte

I’m replicating Postgres -&gt; Postgres. Airbyte reported a successful sync, but zero rows were copied over for a few tables.

*Is this your first time deploying Airbyte*: No
*OS Version / Instance*: Ubuntu 20
*Memory / Disk*: t3.medium (8GB memory, not sure disk)
*Deployment*: Docker
*Airbyte Version*: 0.27.0-alpha
*Source name/version*: Postgres 0.3.6
*Destination name/version*: Postgres 0.3.6
*Step*: Manual sync
*Description*: I see a “Succeeded”, but I have zero rows for many tables. Using CDC.

The only errors I see are:

```2021-07-12 20:10:45 INFO () JsonSchemaValidator(test):76 - JSON schema validation failed. 
errors: $: unknown found, object expected
2021-07-12 20:10:45 ERROR () DefaultAirbyteStreamFactory(lambda$create$1):83 - Validation failed: null```

Update - still failed on a t3.xlarge. No memory issues, just a silent success (using 0.27.1!)

<@U01TMUWMWMP> it’s still running, but there are some errors in the logs. Seems like there’s another OOM problem. Attached below:

Using a t3.xlarge right now
