terragrunt apply fails for module

[jamie3]

I am using a module from the registry and it is failing. Note: Running this in vscode bash shell.

Steps to reproduce

export TERRAGRUNT_DOWNLOAD=/c/.terragrunt-cache
terragrunt init
terragrunt apply

}

I verified the module and tf files were downloaded by going to the terragrunt cache folder.

If I just run terraform init in the path where the .tf files are it works.

What does your terragrunt.hcl look like?

[jamie3]

terraform {
    source = "${get_terragrunt_dir()}/../../../../../infrastructure//waf"
}

# Include parent settings
include {
    path = "${find_in_parent_folders()}"
}

inputs = {
    # IP CIDR which the WAF will block
    blacklisted_ips = [
        "37.9.0.0/20",      # 4096 RU Russian Federation
        "37.9.16.0/20",     # 4096 KZ Kazakhstan
        "37.9.32.0/20",     # 4096 RU Russian Federation

    ]
}

Doing more investigation is seems this is a terragrunt issue.

infrastructure\waf
live\production-account\production-env\us-west-2\waf

When I run terraform init in infrastructure\waf it successfully downloads the module.

When I run terragrunt init in the live\production-account\production-env\us-west-2\waf folder I get the following error:

Initializing modules...

If I change my terragrunt download directory to export TERRAGRUNT_DOWNLOAD=/c/.terragrunt-cache it works.

Using Windows 10, vscode bash shell.

[jamie3]

After I change the download directory I get the error from my original post. I found the issue:

My directory structure is as follows:

infrastructure\modules\my-module   (locally developed modules go here) 
infrastructure\waf

export TERRAGRUNT_DOWNLOAD=/c/.terragrunt-cache
cd live\production-account\production-env\us-west-2\waf
terragrunt init

For whatever reason the module isnt being downloaded as there is no main.tf.

If I run terraform init in the infrastructure/waf folder and ls -la .terraform/modules the main.tf is present.

I am seeing a similar issue the past couple of days but in my case, if I delete .terragrunt-cache it will work for about 1 run, then it will go back to complaining about unsupported arguments again.

Any update on this?
