AI generated answer (using internal Slack threads):

The error "Shipping partner plug-in is not specified" typically occurs when the shipping method or shipping partner is not correctly specified or missing in the record. To resolve this issue, you should ensure that the shipping method and shipping partner are correctly set in the record. You can do this by going to the shipping tab of the record and checking if the shipping method and shipping partner fields are filled out correctly. If the fields are filled out and you're still encountering the error, it might be due to a workflow or script running on the record that is causing the issue.
