I am trying to create AWS SFTP server using terraform script.

I am able to validate using terraform validate command and able to get plan using terraform plan as well

but I am getting below error while trying to run terraform apply command

Error: Error creating Transfer Server: InvalidRequestException: Must specify IdentityProviderType with IdentityProviderDetails on .terraform/modules/sftp/sftp.tf line 1, in resource "aws_transfer_server" "sftp": 1: resource "aws_transfer_server" "sftp" {

I have provided the identity_provider_type = "SERVICE_MANAGED" in my script but still i am getting the error and unable to create AWS SFTP server.

Here is my scripts

sftp.tf

provider "aws" {
   version = "~> 2.0"
   region  = "us-east-1"
}

resource "aws_transfer_server" "sftp" {
  identity_provider_type = "SERVICE_MANAGED"
  invocation_role = "arn:aws:iam::<id>"

  tags = {
        NAME     = "test-sftp"
  }
}

main.tf

provider "aws" {
    version = "~> 2.0"
    region  = "us-east-1"
}

module "sftp" {
    source = "/home/sasi/TerraForm/terraform-scripts/modules/sftp"
    aws-transfer-server-name = "test-sftp"
    iam-role-name-for-sftp = "test-sftp-role"
    s3-access-policy-name = "s3-specific-bucket-access"
    sftp-user-name = "sasi-sftp"
    sftp-s3-bucket-name = "/sasi-learn-test-bucket"
    ssh-public-key-file-location = "${file("/home/sasi/TerraForm/terraform-scripts/modules/sftp/rsa.pub")}"
}
