Motivation and Context

the below error appears when using this module with the latest aws provider v3.2.x

Error: Unsupported argument

on .terraform/modules/cassandra-iam/instance_profile/main.tf line 3, in resource "aws_iam_instance_profile" "profile":
3: roles = [aws_iam_role.role.name]

An argument named "roles" is not expected here. Did you mean "role"?

Thanks for your contribution.

Could you add a version constraint for the aws provider inside the module? That will help with current installs of this module and will force users to use a newer version of the provider.

Something like:

terraform {
  required_providers {
    aws = {
      version = ">= 3.26.0"
      source = "hashicorp/aws"
    }
  }
}

There's already a terraform block in the versions.tf file that you can reuse
