Sls deploy -s test => "stack with id XX does not exist"

In my serverless.yml, I’m setting an environment variable like so:
USERPOOL_ARN: ${cf:${self:provider.environment.STACK_NAME}.UserPoolArn}

Works fine when I deploy to the default stage, but when I try to deploy to a different stage, I get an error saying stack does not exist. I checked in cloudformation and the stack definitely exists.

However, this works:
AWS_PROFILE=testProfile sls deploy -s test

Just realized this is the wrong place to post. I opened an issue:

Can’t figure out how to delete the post, tho :thinking:
