Hi Everyone I'm new to Pulumi and tried below sample project https://github.com/pulumi/infrastructure-as-code-workshop/tree/master/labs/aws/in-person/python/lab-01 Then I got this error doing step 5(Making Your Stack Configurable)

error: Program failed with an unhandled exception:

Hope you can help me on this. Thanks in advance.

can you share how your code looks? which step did you get stuck on?
