hclvalidate didn't works on hcl that contains dependency

[kamontat]

Describe the bug

When I try to run hclvalidate command on terragrunt.hcl that contains dependency, I got dependency.namespace is object with 1 attribute "inputs".

When I try to run hclvalidate command with --terragrunt-hclvalidate-show-config-path, I got json: cannot unmarshal string into Go struct field CtyJSONOutput.Value of type map[string]interface {}.

Steps To Reproduce

Create terragrunt.hcl with dependency field, and run hclvalidate on that directory.

dependency "namespace" {
  config_path = "${get_terragrunt_dir()}/../namespace"
}
inputs = {
  namespace = dependency.namespace.outputs.namespace
}

Expected behavior

Similar result as run tofu validate.

Nice to haves

Hey @kamontat ,

Does that dependency have any outputs? Has it been applied yet?

If not, you may need to mock those outputs so that the relevant cty values are available for HCL parsing at this phase.

Let me know if any of that doesn't make sense!
