I installed target-parquet to export some test data. When I run the job, the loader is falling: "Run invocation could not be completed as block failed: Loader failed" Enabling the debug log, this seems to be the underlying problem: AttributeError: Can't pickle local object 'persist_messages.<locals>.consumer' . Any ideas about what could be happening and how to solve it? I am running Python 3.9.1 and Meltano 2.0.2

I have this issue, too. Does anyone has solution for this ?

@cesar_garcia_saez Were you ever able to find a solution to this? I've just come across the same problem
