Unable to run terraspace plan with modules

Terraspace
1

I am attempting to run terraspace plan in a stack that references a module, the output looks good when I run terraspace init, it successful fetches the module however when I run terraspace plan I get an error that the module isn’t installed.

Below is my output:

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.
If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.

Is there an extra step I need to install modules within the Terraspace modules folder?

Naw. There shouldn’t be an extra step. :thinking:

Thinking give one of the Getting Started Guides a try.

https://terraspace.cloud/docs/learn/aws/review-project/

It generates an example that uses a module. And it doesn’t require any extra steps.

I had to run terraform get within the stack using the module and now terraspace plan runs correctly :tada:

Thanks!

I am also seeing the same issue with 2.2.15.
There is nothing really special but just can’t figure out what’s causing the problem.

app → modules → common-tags

locals {
  tags = {
    ManagedBy    = "terraform"
    Environment  = "<%= expansion(':ENV') %>"
    Stack        = "<%= expansion(':MOD_NAME') %>"
    Region       = var.organisation
    Organisation = var.organisation
    Project      = var.project_name
  }
}

app → stacks → common-tags

module "common_tags" {
  source = "../../modules/common-tags"

  environment  = var.environment
  project_name = var.project_name
}

Small update:
If I run terraspace up es then everything works as expected. I suppose that terraspace build es is not initializing the TF modules
