Image file in DB entry does not

I try to have the user select an image file, and then insert into a db however I get this db error "entity line with null key is not found in NblNhIncsubmission."

If you see my picture below you can see my code is correctly downloaded the file and update the "Attachment" field, but it throws an error inserting the entire form in the db

Here's the PB I need to insert in (circled is the column I'm inserting the NblNhIncsubmission DB)

Here is my page jspx code:
