Hello.

Hi guys, my name is Christian. I’m here trying to figure out why I am getting this message:

```
Previewing update (benton-uat0):

     Type                     Name                             Plan       Info

Diagnostics:
  aws:ec2:Vpc (uat-backend-vpc9098098090909809):
    error: Duplicate resource URN 'urn:pulumi:benton-uat0::benton::aws:ec2/vpc:Vpc::uat-backend-vpc9098098090909809'; try giving it a unique name

error: an error occurred while advancing the preview
```

I’ve tried renaming the resource, deleting the stack then creating it again, using another stack, and nothing helps. I keep getting the same error.
