Need to mass update invoice pay group and payment terms using Visual Builder Add-in for Excel

Summary:

We have a large number of Payables invoices which need pay groups and payment terms updating.

For ease of use we would like to use Visual Builder Add-in for Excel, if at all possible. I've seen some community posts which suggests this is possible but can't find any definitive information.

I have successfully used Visual Builder for Excel to mass update POs in the past but can't seem to get it to work for Payables Invoices.

When trying to use /fscmRestApi/resources/11.13.18.05/invoices/describe I get the following error:

The operation failed due to an internal server error. Contact the system administrator to review the server logs to determine the actual cause. (VBAFE-00109)
