How can I access a folder outside of the terraform root module?

Question

I am trying to deploy a lambda using terraform. One of the steps in the lambda module zips up the source folder for the lambda. However, when I run the following code I am met with this error:
Error: error archiving directory: could not archive missing directory: ./../hello-world

This is my current folder structure

Here is my lambda terraform for the zip step:

data "archive_file" "lambda_hello_world" {
  type = "zip"

  source_dir  = "${path.root}/../hello-world"
  output_path = "${path.root}/../hello-world.zip"
}

Pipeline code:

name: Deploy Infrastructure

on:
  push:
    branches:
      - master

jobs:
  terraform:
    name: 'Terraform'
    runs-on: ubuntu-latest
    defaults:
      run:
        working-directory: './terraform/'
    steps:

    - name: Checkout Repo
      uses: actions/checkout@v3

    - name: Setup Terraform
      uses: hashicorp/setup-terraform@v1
      with:
        # terraform_version: 0.13.0
