My time column would have the default value of current_timestamp() if I went to the table properties after doing the identical action in the same DBR 12.2 LTS runtime.

However, it would fail if I attempted to add data to a target table that had one more column (the default time column) than the values I was adding to it : Cannot write to 'spark_catalog.gold.xxxxxxx', not enough data columns; target table has 19 column(s) but the inserted data has 18 column(s).

Do you know why this might be occurring?
