James Hartig commented on CASSGO-42:
------------------------------------

Another issue is that `MapScan` is not checking the `err` response from `RowData`

> `applied = dest["[applied]"].(bool)` is in `MapExecuteBatchCAS` but if the iterator errored then the map might be empty and then `panic: interface conversion: interface {} is nil, not bool` is thrown. We should be checking if the field exists and only panic if it's actually not-nil and not a bool.
