Question

I’m working through the AWS Cloud Development Kit (CDK) tutorial at https://docs.aws.amazon.com/cdk/v2/guide/hello_world.html. Working in CloudShell, I got through step 7 with no trouble; step 6 produced the following template.

Resources:

But when I run step 8, executing cdk deploy, I get the following response:

So, CDK doesn’t recognize the AWS::Lambda::Url resource type that CDK itself included in the template that it generated? I’m getting no clue from the error message as to what to do about this.
