Because you’re trying to use the ARN in the `resources` section (which is just CloudFormation) you can use the intrinsic function [`GetAtt`](http://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/intrinsic-function-reference-getatt.html).

Here’s what you need for your RoleARN:

```auto
RoleARN:
  Fn::GetAtt: [IamRoleLambdaExecution, Arn]

```
