Record Header Attributes for Oracle Bulkload

I am trying to use Oracle Bulkload Origin to read multiple tables from Oracle database. I want to use the tablenames from source to write to destination as files names. 

In the preview I can see some attributes but when I try to capture them in Expression Evaluator they appear null. 

Here is my config for expression evaluator

Is it something to do with oracle version? or data collector version?

I am using 

Oracle Database 21c Enterprise Edition Release 21.0.0.0.0 - Production
Version 21.3.0.0.0

SDC version 5.5.0

I can see the jdbc.tables if i use JDBC Multitable Consumer but I want to use Bulkload.
