API works w/ 12.0 but not 12.0.1

I am running a script from the Solarwinds GitHub site for adding groups via API. It works on our instance of Solarwinds 12.0 but not on Solarwinds 12.0.1. In 12.0, the script runs, and returns back the new container ID and there is a new group added. In 12.0.1, the script runs, and returns back the new ContainerID, but the container is not actually added into the web interface or the DB. The Container ID is iterating up though.

What is difference between 12.0 and 12.0.1?   Is there a fix for this problem?
