Create API Gateway with {} in path - amazon-web-services

Question

I need to create API Gateway with {} in path: /from/{date1}/to/{date2}
but was able to generate only following: /from/date1/to/date2
This is what I need:
Here is my code:
resource "aws_api_gateway_rest_api" "api" {
name = "my_api_gateway"
}
resource "aws_api_gateway_resource" "api" {
path_part = "api"
parent_id = aws_api_gateway_rest_api.api.root_resource_id
rest_api_id = aws_api_gateway_rest_api.api.id
}
resource "aws_api_gateway_resource" "from" {
path_part = "from"
parent_id = aws_api_gateway_rest_api.api.root_resource_id
rest_api_id = aws_api_gateway_rest_api.api.id
}
resource "aws_api_gateway_resource" "date1" {
path_part = "date1"
parent_id = aws_api_gateway_resource.from.id
rest_api_id = aws_api_gateway_rest_api.api.id
}
resource "aws_api_gateway_resource" "to" {
path_part = "to"
parent_id = aws_api_gateway_resource.date1.id
rest_api_id = aws_api_gateway_rest_api.api.id
}
resource "aws_api_gateway_resource" "date2" {
path_part = "date2"
parent_id = aws_api_gateway_resource.to.id
rest_api_id = aws_api_gateway_rest_api.api.id
}
resource "aws_api_gateway_method" "method" {
rest_api_id = aws_api_gateway_rest_api.api.id
resource_id = aws_api_gateway_resource.date2.id
http_method = "POST"
authorization = "NONE"
}
resource "aws_api_gateway_deployment" "api" {
rest_api_id = aws_api_gateway_rest_api.api.id
triggers = {
redeployment = sha1(jsonencode([
aws_api_gateway_resource.api.id,
aws_api_gateway_method.method.id,
aws_api_gateway_integration.lambda.id,
]))
}
lifecycle {
create_before_destroy = true
}
}
resource "aws_api_gateway_stage" "api" {
deployment_id = aws_api_gateway_deployment.api.id
rest_api_id = aws_api_gateway_rest_api.api.id
stage_name = "dev"
}
resource "aws_api_gateway_method_settings" "example" {
rest_api_id = aws_api_gateway_rest_api.api.id
stage_name = aws_api_gateway_stage.api.stage_name
method_path = "*/*"
settings {
metrics_enabled = true
logging_level = "INFO"
}
}
resource "aws_api_gateway_integration_response" "response" {
rest_api_id = aws_api_gateway_rest_api.api.id
resource_id = aws_api_gateway_resource.date2.id
http_method = aws_api_gateway_method.method.http_method
status_code = aws_api_gateway_method_response.response.status_code
depends_on = [
aws_api_gateway_integration.lambda
]
}
resource "aws_api_gateway_method_response" "response" {
rest_api_id = aws_api_gateway_rest_api.api.id
resource_id = aws_api_gateway_resource.date2.id
http_method = aws_api_gateway_method.method.http_method
status_code = "200"
response_models = {
"application/json" = "Empty"
}
}
