bug: unhandled message logging causes error

[pnadolny13]

It looks like a new Airbyte message type was added. The tap looks like it handles extra messages gracefully but the logging seems to cause an exception. I wonder if this is a stdout vs stderror issue and the log is being passed over stdout where the target is expecting singer messages to be passed.

I created a branch https://github.com/MeltanoLabs/tap-airbyte-wrapper/tree/handle_control_message to handle the CONTROL type that I ran into but we should probably solve the underlying logging issue so any future new message types are handled too.

Unhandled message: {'type': 'CONTROL', 'control': {'type': 'CONNECTOR_CONFIG', 'emitted_at': 1735850275276.2463, 'connectorConfig': {'config': [....]

The above exception was the direct cause of the following exception:
