   ```
   [INSERT_COLUMN_ARITY_MISMATCH.NOT_ENOUGH_DATA_COLUMNS] Cannot write to `spark_catalog`.`default`.`bug`, the reason is not enough data columns:
   Table columns: `c1`.
   Data columns: `c2`.
   ```
   
   For by-name insert, shall we just say "incompatible data columns"? The number of columns does match here.
