This error (reported by sentry) seems to happen on every prewarm request, every 30 minutes
Aws::CloudFormation::Errors::ValidationError "Either StackName or PhysicalResourceId must be specified."
Running on the latest version of Jets.
Had a look at the Cloudformation SDK changelog & commits (which was bumped to latest when bumping jets) but no luck… https://github.com/aws/aws-sdk-ruby/blob/master/gems/aws-sdk-cloudformation/CHANGELOG.md
Is anybody encountering this?
