I believe I have found a defect in Seed. This is not blocking me, I was able to work around it, but wanted to share... I was in the process of splitting my work-in-progress application to use different AWS accounts - one for Prod, one for Dev. I started with two brand new accounts that had not been bootstrapped by the CDK. I was able to use Seed to deploy my build to Dev as a manually deployment. However, the deployment to prod failed when I attempted to promote the build on Dev to Prod. It failed because the Prod account had not yet been bootstrapped. I was able to work around this by bootstrapping it with the SST cli.

Hey @Frank Faubert, thanks for letting us know. Taking a look..
