I'm using a pipeline from PostgreSQL → BigQuery, and now the sync is failing with this error:
java.lang.ClassCastException: class io.airbyte.cdk.load.data.NullValue cannot be cast to class io.airbyte.cdk.load.data.TimestampWithoutTimezoneValue
(io.airbyte.cdk.load.data.NullValue and io.airbyte.cdk.load.data.TimestampWithoutTimezoneValue are in unnamed module of loader 'app')
This wasn’t happening before — the sync worked fine when I were on a < 3.0.x version of the connector.
Unfortunately, downgrading isn’t an option at the moment because v3.0.x no longer uses the airbyte_internal dataset for temporary data storage, which we’ve already removed/configured around.
Any ideas on how to work around this or if a patch is on the way?
