Invalid resource attribute MytargetGroup for resource Outputs

Question

I'm looking to get arn output of the target group. What is the correct way? I've tried the following and nothing works so far.

```
  ### Target group ###

MyTargetGroup:
    Type: 'AWS::ElasticLoadBalancingV2::TargetGroup'
    Properties:
      HealthCheckEnabled: true
      HealthCheckIntervalSeconds: 30
      HealthCheckPath: /
      HealthCheckProtocol: HTTP
      HealthCheckTimeoutSeconds: 5
      HealthyThresholdCount: 5
      Matcher:
        HttpCode: "200,302"
      Name: target-group-1
      Protocol: HTTP
      Port: 80
      UnhealthyThresholdCount: 2
      VpcId: !ImportValue vpc-id

#### Outputs ####
  
  Outputs:
    MyTargetGroupOutput:
      Value: !GetAtt MyTargetGroup.TargetGroupArn

```

According to this document, it should work as I have above, but it doesn't.

Accepted Answer

Could it be an indentation problem? The `Outputs` section should be at the same level as the `Resources` section.
