Terragrunt graph not working correct with find_in_parent_folders

[mueller-tobias]

Describe the bug We're evaluating terragrunt graph as an alternative to run-all. But it seems to have difficulties with find_in_parent_folders. We've tested a little bit with the example live infrastructure repo but when we run the terragrunt graph plan command for example in the webserver directory

A normal terragrunt run-all plan/apply is working without problems.

Since our production repository is leaned on this example we can't switch/test our pipeline to the new feature.

ERRO[0000] Error processing module at '/tmp/terragrunt-infrastructure-live-example/terragrunt.hcl'. How this module was found: Terragrunt config file found in a subdirectory of /tmp/terragrunt-infrastructure-live-example. Underlying error: /tmp/terragrunt-infrastructure-live-example/terragrunt.hcl:9,41-64: Error in function call; Call to function "find_in_parent_folders" failed: ParentFileNotFoundError: Could not find a account.hcl in any of the parent folders of /tmp/terragrunt-infrastructure-live-example/terragrunt.hcl.

ERRO[0000] Unable to determine underlying exit code, so Terragrunt will exit with error code 1 

To Reproduce Clone the terragrunt-infrastructure-live-example Repository add the S3 and AWS values and try a terragrunt graph plan

Expected behavior It should run the plan command on all dependencies.
