Hi,
The dependencies should be in your terragrunt.hcl. The dependencies main purpose is to guarantee correct execution order when you’re applying or destroying infrastructure with the *-all -commands.
Normally your live only contains the terragrunt.hcl for passing variables into your infrastructure-modules. The modules is where you use the outputs and the terraform dependency hierarchy - which is a bit different from the terragrunt.hcl dependency declaration.
Hope this clarifies the issue!
