We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

@Vincent, 

From your message, 

I get it if running from a computer cluster but not on my local machine where it returns the correct values without problem.

How are you running the Python/API script (requires a GUI connection) on the cluster? Are you connecting to the cluster with a GUI/desktop connection like VNC, OpenText ETX, X11 forwarding, etc? Â
