Terragrunt not findind folder from source repo

Question

I am using the official Gruntworks samples with the backend (modules) and frontend (live) repos.

I wanted (for reasons beyond the scope of this question) to switch to https as source.

Therefore I am changing the source of this file

terragrunt-infrastructure-live-example/non-prod/us-east-1/qa/mysql/terragrunt.hcl

To

terraform {
  source = "https://github.com/gruntwork-io/terragrunt-infrastructure-modules-example//mysql"
}

The corresponding plan fails:

[15/09/21 9:18:41] ➜  mysql git:(adding_atlantis_config) ✗ terragrunt plan
ERRO[0000] Working dir mysql from source https://github.com/gruntwork-io/terragrunt-infrastructure-modules-example does not exist 
ERRO[0000] Unable to determine underlying exit code, so Terragrunt will exit with error code 1 

How is this possible since mysql dir exists. Here it is.

Answer 1

Should be like terraform { source = "git::https://github.com/gruntwork-io/terragrunt-infrastructure-modules-example//mysql" }
