Thank you @rdblue - I tried your suggestion but unfortunately getting
another error, I added the following just before the table overwrite and it
didn't help:
`spark.sql(f"""ALTER TABLE iprod.test_schema.example SET TBLPROPERTIES
('format-version' = '2')""")`
as mentioned in the Tabular article:
https://tabular.io/blog/iceberg-format-version/
and getting this error:
`Caused by: java.lang.NullPointerException: Cannot find source column: 1
