I’m trying to create a connection in Airbyte 0.61.0 (deployed in Docker containers in a Linux Server) using PostgreSQL (conector version 3.4.10) as source and Kafka (conector version 0.1.10) as destination. The settings can not be completed since in step 3-Select Streams an error occurs: Discovering schema failed – Failed to run schema discovery.

I already checked the connections with Postgres and Kafka and everything is working, also the user grants on Postgres Schema is correctely set. The Postgres database that I’m trying to connect is just a test one with only one small table and only the default schemas, I passed ‘public’ schema in postgres conector configs.

Any information on how to fix this will be very helpfully!

Thanks in advance!

I tryed Detect Changes with Xmin System Column and Scan Changes with User Defined Cursor in postgres conector but nothing was changed. Also, connecting to other Postgres database or schemas results in the same error.
