Cloudformation script fails on creating lambda due to missing IAM role

Describe the bug We (@npalm and @joostwestra have created the MLOps framwork via the stack published on AWS (ttps://solutions-reference.s3.amazonaws.com/aws-mlops-framework/latest/aws-mlops-single-account-framework.template). All worked fine till today. As of today we got an error during creation of the stack. Creating a lamba fails with an error that the required role not exists. However the specific role was created before. See log below.

To Reproduce

1. Create cloud formation stack based on: ttps://solutions-reference.s3.amazonaws.com/aws-mlops-framework/latest/aws-mlops-single-account-framework.template (used region eu-west-1)
2. Just wait, after a few mintues the stack will rollback.

Expected behavior Should succeed (as before)

Please complete the following information about the solution:

• latest

To get the version of the solution, you can look at the description of the created CloudFormation stack. For example, “(SO0136) - AWS MLOps Framework. Version v1.0.0”.

• Region: eu-west-1
• Were there any errors in the CloudWatch Logs?
