Not able to tag autoscaling group created by EKS Managed Node Group

[sparsh-anurag]

HI, I am trying to use this code in order to tag asg group, it is working when all the resources are already created. but when I am trying to run it from scratch I am getting this error

│ Error: Invalid for_each argument
│
│ on modules/eks/main.tf line 144, in resource "aws_autoscaling_group_tag" "example":
│ 144: for_each = toset(
│ 145: [for asg in flatten(
│ 146: [for resources in aws_eks_node_group.worker-nodes.resources : resources.autoscaling_groups]
│ 147: ) : asg.name]
│ 148: )
│ ├────────────────
│ │ aws_eks_node_group.worker-nodes.resources is a list of object, known only after apply
│
│ The "for_each" value depends on resource attributes that cannot be determined until apply, so Terraform cannot predict how many instances will be created. To work around this, use the -target
│ argument to first apply only the resources that the for_each depends on.

The code block which I am using

resource "aws_autoscaling_group_tag" "example" {
for_each = toset(
[for asg in flatten(
[for resources in aws_eks_node_group.worker-nodes.resources : resources.autoscaling_groups]
) : asg.name]
)

autoscaling_group_name = each.value

tag {
key = "Name"
value = "Worker"
propagate_at_launch = true
}
depends_on = [
aws_eks_node_group.worker-nodes,
aws_eks_cluster.eks,

]
}
