Error: #123010 A package(s) in this shipment contains a warning

This is an intermitent error that appears to be related to UPS June 2023 Ship API updates. It's super confusing as there really is no problem with packages and the error text contains something like "TRANS ID: ABRC1686065601653-6F VERSION: null" which is not helpful at all.

We have contacted UPS Support about this error and they are working to resolve on their backend.

Update 6/13/23 - UPS has not yet resolved so we have updated NRGship for UPS so that the dialog no longer appears for Error 123010. If you quit and re-open the app it should ask you to update to Version 1.6.17
