I'm getting the following error every time sync quickbooks is run.

Errors are Listed Below: There was an error when saving a Items list, element "". QuickBooks error message: The name of the list element cannot be blank. There was an error when saving a Items list, element "".

The only two items sync so far are:

1) one single customer account
2) one single product

Can someone direct me how to trouble shoot this issue?

Thanks
