Sync Error: The transaction is empty

Here is an example of the error message:

Processing invoice #I220519289.
SYNC ERROR: An error occurred creating invoice I220519289. Details: An error occurred importing invoice -- Error info: Detail=There was an error when saving a Invoice. QuickBooks error message: The transaction is empty., Status=3180, Code=Error

 

Here's a screenshot of Invoice I220519289:

 

There is only 1 line item on this invoice, and it has a price of $0.

QuickBooks does not allow an invoice where all of the line items have a price of $0.

At least 1 line item on the invoice must have a price, otherwise, QuickBooks doesn't consider it to be a valid invoice.

 

To resolve this, simply use the Advanced Toolbox to exclude this invoice from the next sync.

Here's how:  Exclude Invoice from Next Sync

 

After excluding this invoice, re-run the sync, and it will be successful.
