Hi,

I"m using typescript aws template and now the serverless.yml is serverless.ts.  
However, i’m have a problem on type declaration to define my resources.

Sample in serverless.yml (working):

```auto
resources:
  Resources:
    IamRoleLambdaExecution:
      Properties:
        Path: /eng-roles/
        PermissionsBoundary: "arn:aws:iam::#{AWS::AccountId}:policy/roles-boundary"

```

Try #01 in serverless.ts (not working)

```auto
  resources: {
    Resources: {
      IamRoleLambdaExecution: {
        Type: "IamRoleLambdaExecution",
        Properties: {
          Path: "/eng-roles/",
          PermissionsBoundary: "arn:aws:iam::#{AWS::AccountId}:policy/roles-boundary"
        }
      }
    }
  }

```

Try #02 in serverless.ts (also not working)

```auto
  resources: {
    Resources: [ 
      { 
        Type: "IamRoleLambdaExecution",
        Properties: { 
          Path: "/eng-roles/",
          PermissionsBoundary: "arn:aws:iam::#{AWS::AccountId}:policy/roles-boundary"
        }
      }
    ]
  }

```

How can i adjust my resource definition?

Thanks
