An argument or block definition is required here - terraform

Question

I am using kubernetes_network_policy resource. I am trying loop over the ports and getting this issue.
╷
│ Error: Argument or block definition required

│ on main.tf line 16, in resource "kubernetes_network_policy" "example-policy":
│ 16: { for i in range(length(val.egress_number)):

│ An argument or block definition is required here.
My Resource
resource "kubernetes_network_policy" "example-policy" {
for_each = var.inputs
metadata {
name = each.value.name
namespace = each.value.namespace
}
spec {
pod_selector {
match_labels = {
app = each.value.selector
}
}
policy_types = each.value.policy
egress {
{ for i in range(length(egress_number)):
ports {
port = egress_number[i]
protocol = egress_protocol[i]
}
}
to {
namespace_selector {
match_labels = {
app = each.value.egress_label
}
}
}
}
}
}
My varibale.tf
variable "inputs" {
type = map(object({
name = string
namespace = string
selector = string
policy = list(string)
egress_number = list(string)
egress_protocol = list(string)
egress_label = string
}))
default = {}
}
My tfvars
inputs = {
app = {
name = "nignx"
namespace = "default"
selector = "nignix-app"
policy = ["Egress"]
egress_label = "play"
egress_number = ["443", "8080"]
egress_protocol = ["TCP", "TCP"]
}
}

You have to use dynamic blocks:
resource "kubernetes_network_policy" "example-policy" {
for_each = var.inputs
metadata {
name = each.value.name
namespace = each.value.namespace
}
spec {
pod_selector {
match_labels = {
app = each.value.selector
}
}
policy_types = each.value.policy
dynamic "egress" {
for_each = range(length(each.value.egress_number))
content {
ports {
port = each.value.egress_number[egress.value]
protocol = each.value.egress_protocol[egress.value]
}
to {
namespace_selector {
match_labels = {
app = each.value.egress_label
}
}
}
}
}
}
}
Instead of using range and length, one could also use zipmap in your case.
