Checkout out older repo that worked fine and am getting such error - any ideas what might be going wrong here?

Sounds like you don't have a python environment, you aren't in a venv, or you haven't installed the dependencies.

Yes, I think this error is indicating that you’re using the Automation API without having the Pulumi binary in your path. You must first install Pulumi before using Automation API; unfortunately it’s not enough to install the @pulumi/pulumi Python package.

Thanks folks! Installed pulumi through brew - works like a charm now!

Glad to help, friend!
