Enabling Managed Updates for Elastic Beanstalk with terraform - amazon-web-services

Question

I am trying to enable managed updates with terraform but i am getting the following error
Error: ConfigurationValidationException: Configuration validation exception: Invalid option specification (Namespace: 'aws:elasticbeanstalk:managedactions', OptionName: 'ManagedActionsEnabled'): You can't enable managed platform updates when your environment uses the service-linked role 'AWSServiceRoleForElasticBeanstalk'. Select a service role that has the 'AWSElasticBeanstalkManagedUpdatesCustomerRolePolicy' managed policy.
Terraform code:
resource "aws_elastic_beanstalk_environment" "eb_env" {
setting {
namespace = "aws:elasticbeanstalk:managedactions"
name = "ManagedActionsEnabled"
value = "True"
}
setting {

name = "ServiceRoleForManagedUpdates"
value = aws_iam_role.beanstalk_service.arn
}
setting {

name = "elastic-beanstalk-service"
roles = ["${aws_iam_role.beanstalk_service.id}"]
policy_arn = "arn:aws:iam::aws:policy/AWSElasticBeanstalkManagedUpdatesCustomerRolePolicy"
}
I did attempt to create a linked service role but that is not the solution for the error above.
setting {
namespace = "aws:elasticbeanstalk:managedactions"
name = "ServiceRoleForManagedUpdates"
value = aws_iam_service_linked_role.managedupdates_eb.arn
}

I was missing the following settings
setting {
namespace = "aws:elasticbeanstalk:environment"
name = "ServiceRole"
value = aws_iam_role.beanstalk_service.id
}
