AWS Terraform Error registering targets with target group

Getting the error while attaching aws_alb_target_group_attachment. InvalidTarget: The following targets are not in a running state and cannot be registered

resource "aws_alb" "rancher-ctl-host-alb" {      name = "rancher-ctl-host-alb"      internal = false      load_balancer_type = "application"      ip_address_type  = "ipv4"        subnets = ["${data.aws_subnet_ids.vpc_subnets.ids}"]      security_groups = [          "${data.terraform_remote_state.core.rancher-ctl-host-alb-sg-id}"      ]  }  

create an application load balancer listener

resource "aws_alb_listener" "rancher-ctl-host-alb-listener" {      load_balancer_arn = "${aws_alb.rancher-ctl-host-alb.arn}"      port = 80      protocol = "HTTP"        default_action {          type             = "forward"          target_group_arn = "${aws_alb_target_group.rancher-ctl-host-target-group.arn}"      }  }  

create the application load balancer target group

resource "aws_alb_target_group" "rancher-ctl-host-target-group" {      name = "rancher-ctl-host-target-group"      port = 8080      protocol = "HTTP"      vpc_id = "${data.terraform_remote_state.core.default-vpc-id}"  }  

attach the three hosts to the target group

resource "aws_alb_target_group_attachment" "rancher-ctl-host-target-group-instances" {    target_group_arn = "${aws_alb_target_group.rancher-ctl-host-target-group.arn}"    target_id        = "${aws_spot_instance_request.rancher-ctl-host.*.spot_instance_id[count.index]}"    port             = 8080    count            = 3  }
