All values showing as None

[pmogren]

Hi, I'm brand new to Daft. I'm trying to read Databricks managed delta lake tables via Unity Catalog using its credential vending. Having worked around the issues in #3708 I am able to list catalogs and tables, load a table, count the rows, and discover the columns. However when I df.show(), every single value is None. If I use df.where(col("account_id") != None), I get no rows. Any idea why?

Hey @pmogren, could you share a code example with us, please?

Looks like my issue is #1955 . I will see if I can find a table without column mapping to test with.

Confirmed the issue was that the table had column mapping enabled.

Thanks for confirming! Let me see if we can bump the priority on getting a fix in for column mapping. cc @raunakab
