Hello, I'm new in Nifi and have a problem by inserting JSON values into a SQL Table. My JSON contains information about TyreDatas. There it is possible that some field are not set. So I need to import a NULL value into SQL Table. But if I use the ReplaceText pattern all NULL values are inserted as a nvarchar "null" value, which can make problems. F.e. if the LoadIndex isn't set, I get the value 'null' inside the SQL Table.
