Hi, Just getting started with SST. I am trying to deploy a nearly empty stack as just beginning to define the infrastructure for a new project.

When I run `npx sst start`, I get a ‘You are not authorized to perform this operation.’ error. Unfortunately, this error does not tell me what authorization I am missing. I would hope to see a specific IAM Permission that my account is lacking, so that I know how to fix the problem.

Is there a guide somewhere that helps with getting permissions set up to use SST? Or some way to make it tell me what permission I am missing?

The account I am using to deploy this has sufficient permissions to do it under CDK, and I am just moving this simple CDK stack over to use SST.

```auto

I was able to start the stack for a new project created with:

```auto
npx create-serverless-stack@latest my-sst-app

```

So I guess the lack of permission must be something that I am creating in my stack, rather than deployment permissions in general.

Would be nice to get some more detail on this error though - the stack did succesfully deploy in CloudFormation without error.

That’s a bit strange. Let me know if you run into this again.
