Data Import Manager - Pending GL Transactions

Hello!

I'm trying to setup a data import task for pending gl transactions and am getting this error when running:

Description: "output "JournalDetl$" (9)" contains no output columns. An asynchronous output must contain output columns.

We have a sales order import working correctly. I've setup this GL transaction task the same way and yet am getting this error. 

I'm not sure how to fix this. Any ideas?

Thank you!
