An argument or block definition is required here

Terraform
1

Hi All,
I am seeing the following error when i run terraform apply. Any ideas how to fix it?

Terraform version= Terraform v0.12.2 provider.aws v2.47.0

Error: An argument or block definition is required here. To set an argument, use the equals sign “=” to introduce the argument value. This is giving the error for the line below(password_policy.temporary_password_validity_days = 7):

resource “aws_cognito_user_pool” “admin_cognito_pool” {
name = “dummy-pool”
username_attributes = [“email”]
auto_verified_attributes = [“email”]
admin_create_user_config {
allow_admin_create_user_only = true
#unused_account_validity_days = 7
password_policy.temporary_password_validity_days = 7
}

This works for me (using terraform fmt)

resource "aws_cognito_user_pool" "admin_cognito_pool" {
  name                     = "dummy-pool"
  username_attributes      = ["email"]
  auto_verified_attributes = ["email"]
  admin_create_user_config = {
    allow_admin_create_user_only = true
    #unused_account_validity_days = 7
    password_policy.temporary_password_validity_days = 7
  }
}

Dunno if it’s functional.

Hi,
I tried using the same block which you pasted and now it fails with the below error when running Terraform plan. Any ideas how to fix it?

Error: Unsupported argument

on CreateUserPool.tf line 25, in resource “aws_cognito_user_pool” “admin_cognito_pool”:
25: admin_create_user_config = {

An argument named “admin_create_user_config” is not expected here. Did you
mean to define a block of type “admin_create_user_config”?

Ok, so fmt was checking for syntax only. My fault.

Yeah i ran fmt and it fixed the syntax of my file. On some research looks like you have to declare variables in variables.tf so i am doing that now to check if it fixes the issue.

Try this one:

resource "aws_cognito_user_pool" "admin_cognito_pool" {
  name                     = "dummy-pool"
  username_attributes      = ["email"]
  auto_verified_attributes = ["email"]
  admin_create_user_config {
    allow_admin_create_user_only = true
    #unused_account_validity_days = 7
  }
  password_policy {
    temporary_password_validity_days = 7
  }
}

Hi,
Thanks for helping me out on this. Appreciate it. I ran terraform plan again and now its complaining about this here: You can copy the below script as is and it should work for you:
Error:
on main.tf line 40, in resource “aws_cognito_user_pool” “admin_cognito_pool”:
40: schema = [
An argument named “schema” is not expected here. Did you mean to define a
block of type “schema”?

resource “aws_cognito_user_pool” “admin_cognito_pool” {

auto_verified_attributes = [“email”]
admin_create_user_config {
allow_admin_create_user_only = true
#unused_account_validity_days = 7
}
password_policy {
temporary_password_validity_days = 7

Hi,
so i was able to fix the issue. Terraform version was causing the issue. Downgraded to 11.13 and it worked.

In case you have copy pasted the code online, try to rewrite the code as there may be some invisible characters. Got the same error, fixed it by rewriting.

That was it , I replaced every special character by typing them and it worked - Thank you
