Copy attachment from record producer variable to record is not working

[Renu9]

I am trying to copy an attachment from variable in record producer to record with the below BR, but its not working

I am using Async insert BR on the table (x_as_request) in scoped app.

In line number 5, im getting 'x_as_request' table in the log.

In the attachment table, I am seeing the table name as ZZ_YYsc_cart_item and the table sys id is empty. 

I assume table sys id should not be empty . Please help me here attachment is not getting added to record.

the attachment variable approach should work
