Is there a secret list of column names for a successful submission?

I’ve submitted 10+ times now with two different models that have received Bad Prediction status for all of them. Some of them are my own error. I have a schema validation script that follows the example parquet submission file. What am I missing? Can someone share what the expected column names are for a successful submission?

You are including an extra “cluster” column:

Thanks @enzo that makes sense… my validation schema looks for the correct columns but doesn’t check for extra columns. Thanks for helping me out.

We are also at fault.
New competition give a lot more details, but data crunch is running on an old system which make hard to bring these new improvement…

Apologies for the confusion.
