Terraform Core Version

1.5.7

AWS Provider Version

Affected Resource(s)

aws_appconfig_extension action_point > role_arn

Expected Behavior

I should be able to create an extension pointing to the default event bus using something like, without a role_arn as not required by AWS.

Actual Behavior

role_arn is required and I can't create an extension pointing to eventbridge as

error without role_arn specified

error with custom role_arn specified
