AWS SSM Parameter Store lookup not working


Concourse is running with an IAM role that allows SSM access but when putting in a templated pipeline it fails to find the variables. Do i need to hardcode the credentials at atc start? Because in the documentation it says it can fetch them dynamically.
Concourse will attempt to use environment variables or the instance credentials assigned to the instance.

But after this i don’t see any mentions of failed attempts in the concourse web logs or CloudTrail.
