I started to test pulumi with AWS and by accident got pulumi to disconnect while creating an EKS cluster. The cluster was created but pulumi could not recognize it. I tried to use the refresh command, but it seems like it does not pull information from AWS about what resources are created. Pulumi can only know about resources that it connects with URN. Is there a way to ask pulumi to pull the correct state from AWS? I could start adding tags with a UUID to every component (basically like the URN) and use Get functions of resources to look for those who were created, but this is less then ideal.

Did you try to import it? If the process was cancelled then it might not have registered it in the stack.
