)Which action should the developer take to resolve this error?
Contact AWS Support to report an issue with the Auto Scaling Groups (ASG) service.
Add a DependsOn attribute to the ASGInstanceRole12345678 resource in the CloudFormation template. Then delete the stack.
Modify the CloudFormation template to retain the ASGInstanceRole12345678 resource. Then manually delete the resource after deployment.
Add a force parameter when calling CloudFormation with the role-arn of ASGInstanceRole12345678.
Explanations:
Contacting AWS Support may help if there is a service issue, but it does not directly resolve the error encountered during the deletion of the resource. The issue is likely related to dependencies or resource status, which can be addressed without external support.
Adding a DependsOn attribute does not apply here because it is intended to control the order of resource creation, not deletion. Since the error is occurring during deletion, this option will not resolve the issue.
Modifying the CloudFormation template to retain the ASGInstanceRole12345678 resource allows the stack deletion to succeed without deleting this specific resource. The developer can then manually delete the resource afterward, effectively bypassing the issue.
There is no “force parameter” option available in CloudFormation for resource deletion. CloudFormation does not support a force delete mechanism; deletion must respect the dependencies and state of the resources.
I rank that the answer is:
Modify the CloudFormation template to retain the ASGInstanceRole12345678 resource. Then manually delete the resource after deployment.
