We started getting errors on our Asana API integration since Yesterday evening. After diving into it we were able to fix it by typecasting the project, collaborators and assignee ID numbers to strings.
After looking into the Active deprecations table we found out that the activation date of that deprecation was August 13 Build an app with Asana
As usual we are planning on fixing the deprecation before the end date, but it seems the deprecation is broken?
