Receiving Error Code 10007 -> GetSellingManagerTemplates -> API v967

Hello,

I am investigating an error for which I am receiving when calling GetSellingManagerTemplates. Previously, all calls made from my application were working properly. It appears there was possibly a bug introduced in the latest API changes made on Nov 20, 2020. Can you please advise as to why I would be seeing an API server side error when trying GetSellingManagerTemplates?
