sharepoint-add-in

I got an error stating that the "Tenant app deployment is only supported in the app catalog site. The current site is not the app catalog site.", even if the current site very much IS an app catalog site? There might be an easy fix!...

Luckily, SharePoint Add-ins (or App Parts, like they were called earlier) are slowly getting killed and rooted out of all the sites they once were deployed to - and I don't think anyone's going to miss them....
