Hello,  
unfortunately this is a long know but in the Simba JDBC driver provided by Google. It does not support the usage of NULL values. For more details please see this [post](https://forum.knime.com/t/google-big-query-loading/29127/8).  
If you only want to insert data into BigQuery I suggest you use the [DB Loader](https://kni.me/n/hp8L4I_m6lJfldj5) node which uses another API and is much faster.  
Bye  
Tobias
