Terraform backend setup issues

what's the "source" of module "dashboard_cert"? Any chance it's a transitively-included module?

[kuza55]

It's a public module:

module "dashboard_cert" {
  source  = "terraform-aws-modules/acm/aws"
  version = "~> 4.0"

[lilatomic]

Oh, seems we're swallowing errors during init:

╷
│ Error: Failed to download module
│ 
│ Could not download module "dashboard_cert" (../mod1/main.tf:8) source code
│ from
│ "git::https://github.com/terraform-aws-modules/terraform-aws-acm?ref=v4.5.0":
│ error downloading
│ 'https://github.com/terraform-aws-modules/terraform-aws-acm?ref=v4.5.0':
│ git must be available and on the PATH.
╵

fair enough, we don't have git on the path. I think this would affect all public modules.

a quick workaround is to passthrough your path. In pants.toml:

[download-terraform]
extra_env_vars = [
  "PATH"
]

I know it's not ideal.

That resolved the issue with git modules, now I'm seeing local (non-transitive) modules fail too:

$ pants check terraform::
14:36:57.33 [ERROR] Completed: pants.backend.terraform.goals.check.terraform_check - terraform-validate failed (exit code 1).
╷
│ Error: Module not installed

from api.tf:

module api_task {
  source = "./api_task"

I think that was fixed with #20241 . Can you try with one of the releases since then (like version 2.18.2rc2)? If not, you should be able to add the local module as a dependency manually. eg:

terraform_module(
  name="mod",
  dependencies=["./api_task:mod"],
)
