Error "Multiple entries with same key" in VDS preview

Hello,

I’m getting this error when I try to preview a query:

12
121386×169 21.5 KB

What impresses most is the same query executes perfectly when clicking in “Run” button.

Anyone had this same error before?

Cheers,

Would it be possible to share the profile for the failure so we can see the full error (or see if there is a stack trace in server.log?

It may be possible that we have duplicate column names in the same Parquet file, could be different casing, currently we do not support that. Wondering if you can do a "parquet-tools meta " and see if that is true

Thanks
