[Bug]: Cannot add tags to aws_appautoscaling_target resource #31839
Description
Terraform Core Version
v1.4.6
AWS Provider Version
v4.67.0
Affected Resource(s)
aws_appautoscaling_target
Expected Behavior
Terraform should create these resources and manage the tags automatically by seeing the default_tags configuration on the provider
Actual Behavior
When creating the these resources for the first time, we receive the following error:
aws_appautoscaling_target.service_scaling: Creating...
╷
│ Error: creating Application AutoScaling Target (service/content-available-service-nonprod-ecs-cluster/content-available-service-nonprod-ecs-service): ValidationException: The scalable target that you tried to tag already exists.
