`Code: 349. DB::Exception: Cannot convert NULL value to non-Nullable type: While executing ParquetBlockInputFormat: While executing File. (CANNOT_INSERT_NULL_IN_ORDINARY_COLUMN) (version 21.11.1.8356 (official build))`

I need to know, what column is related.

            column_data.emplace_back(timestamp);
