How to get Terragrunt to inclue top level directories - terraform

Question

I'm new to Terragrunt, and I've come across a bit of a situation with how it carries out caching.
This is what my file structure looks like.
├── monitor
│   └── files
│   └── graph
│   └── server
│   └── default
│   └── foo.json
└── terraform
├── env
│   └── stage
│   └── cluster
│   ├── provider.tf
│   └── terragrunt.hcl
├── moduleConfig
│   └── cluster
│   ├── backend.tf
│   ├── random.tf
│   ├── locals.tf
│   ├── outputs.tf
│   ├── main.tf
│   ├── outputs.tf
│   └── variables.tf
└── terragrunt.hcl
But when I run a terragrunt plan and look into the .terragrunt-cache folder, this is what I see.
.terragrunt-cache/
└── KdPWtxpAXZdCe4otk2N9TY1tuQU
└── cwMVo-pYTWr47TeiHN8aORnD8g4
├── env
│   └── stage
│   └── cluster
│   ├── provider.tf
│   └── terragrunt.hcl
├── moduleConfig
│   └── cluster
│   ├── backend.tf
│   ├── random.tf
│   ├── locals.tf
│   ├── outputs.tf
│   ├── main.tf
│   ├── outputs.tf
│   ├── provider.tf
│   ├── terragrunt.hcl
│   └── variables.tf
└── terragrunt.hcl
This results in an undesired plan output, as there are resources in the monitor directory that I need.
This being said, I'm running my terragrunt plan from inside the cluster directory.
├── env
│ └── stage
│ └── cluster
which might explain the issue.
Is there a way to get Terragrunt to include the monitor directory as well, so that the cache contains the full tree with all the files I need?
Thanks.

If you want the monitor directory to get pulled in as well, you might want to take the terragrunt.hcl file, out of the root of the terraform directory and place it on the same path as the monitor and terraform directories.
And then change
terraform {
source = "${path_relative_from_include()}//moduleConfig/cluster"
}
to read
terraform {
source = "${path_relative_from_include()}//terraform/moduleConfig/cluster"
}
This should get the entire structure into the .terragrunt-cache directory.
This might make a good read, if you're curious to see how it works.
