Iteration. For each subnet assign each route of aws client vpn

Hello, I’ve a situation. I’ve created a aws client vpn endpoint, but when I’m trying to assign a route for each subnet, somehow it couldn’t iterate though all provided route(s)

Here is the code:

resource "aws_ec2_client_vpn_route" "endpoint"  {
   for_each               = { for id, subnet in var.subnet : id => subnet }
   target_vpc_subnet_id   = each.value
   client_vpn_endpoint_id = aws_ec2_client_vpn_endpoint.endpoint[0].id
   destination_cidr_block = element(var.routes, each.key))

The variables:

variable "subnet" {
   description = "ID(s) of subnet(s)"
   type        = list(string)
   default     = [ "subnet-0xxxA", "subnet-0xxxB", "subnet-0xxxC" ]

variable "routes" {
   description = "Provided route(s)"
   type        = list(string)
   default     = [ "", "" ]

Expecting: For each provided subnet, assign each provided route.
Got: Only 3 routes are creating, and with random behaviour
