Original GitHub issue: https://github.com/patrickchugh/terravision/issues/171

I try to generate graph with command

terravision draw --source IaC/terraform/prod  --show

and got error:

FileNotFoundError: [Errno 2] No such file or directory: '/Users/user/.terravision/module_cache/terraform-aws-modules_iam_aws;irsa-ebs-csi;/modules/iam-assumable-role-with-oidc'

in .terravision i have:

ls -ls ~/.terravision/module_cache
total 0
0 drwxr-xr-x@ 15 user  staff  480 20 лют.  15:07 terraform-aws-modules_iam_aws;irsa-ebs-csi;

The same error I see with docker.
Is it bug or issue with my local configuration?

Thanks @maxx-ukoo never seen this before can you share your TF module code or a code sample so I can try to reproduce? Is your module referencing another module like in a nested manner ?

@patrickchugh I’m not a DevOps engineer, so I can’t write a minimal configuration, and I also can’t share the production code. But I simply asked Copilot to generate a minimal config. I got:

terraform {
  required_version = ">= 1.4.0"

  required_providers {
    aws = {
      source  = "hashicorp/aws"
      version = ">= 5.0"
    }
  }

  backend "local" {}
}

locals {
  region        = "us-east-1"
  user_pool_id  = "us-east-1_AbCdEf123"       # <-- your Cognito User Pool ID
  app_client_id = "4h5j6k7l8m9n0p1q2r3s4t5u"  # <-- your Cognito App Client ID
}

provider "aws" {
  region = local.region
}

# 1) IAM OIDC provider for the Cognito User Pool
resource "aws_iam_openid_connect_provider" "cognito" {
  url = "https://cognito-idp.${local.region}.amazonaws.com/${local.user_pool_id}"

  # This enforces the 'aud' claim at the provider level
  client_id_list = [local.app_client_id]

  # Amazon Root CA 1 thumbprint commonly used for AWS OIDC endpoints
  thumbprint_list = ["9e99a48a9960b14926bb7f3b02e22da0ecd4e4b5"]
}

# 2) IAM Role assumable via Cognito OIDC
module "iam_assumable_role_with_oidc" {
  source  = "terraform-aws-modules/iam/aws//modules/iam-assumable-role-with-oidc"
  version = "~> 5.0"

  create_role = true
  role_name   = "cognito-oidc-readonly"

  # NOTE: module expects the URL without "https://"
  provider_url = "cognito-idp.${local.region}.amazonaws.com/${local.user_pool_id}"

  # Allow any Cognito user from this pool (tighten as needed)
  oidc_subjects_with_wildcards = ["*"]

  # Attach minimal permissions
  role_policy_arns = [
    "arn:aws:iam::aws:policy/ReadOnlyAccess"
  ]
}

I not sure that it will work after apply but init/plan passed and with command:

docker run -it --rm  -v $(pwd):/project  -e AWS_ACCESS_KEY_ID="ID" -e AWS_SECRET_ACCESS_KEY="KEY" patrickchugh/terravision draw --source /project/

I got:

I found this was related to a version mismatch on the module source terravision was downloading. This is now fixed in the latest version. Can you try agian?

@patrickchugh i have tested with 0.18.0 and it is works.

I have one more suggestion.
Could you update the README and change:

docker run -it --rm  -v $(pwd):/project  -v ~/.aws:/home/terravision/.aws:ro  patrickchugh/terravision draw --source /path/to/terraform_source

to:

docker run -it --rm  -v $(pwd):/project  -v ~/.aws:/home/terravision/.aws:ro  patrickchugh/terravision draw --source **/project/path/to/terraform_source_inside_you_project**

I guess this change can save few minutes for new users.
