Hey, when running the breakdown for a terragrunt repo I am getting the following issue:

Errors:
  Failed to parse the Terragrunt code using the Terragrunt library:
1 error occurred:
        * value is null
goroutine 104 [running]:
runtime/debug.Stack()
        /opt/hostedtoolcache/go/1.19.12/x64/src/runtime/debug/stack.go:24 +0x65
<http://github.com/infracost/infracost/internal/providers/terraform.(*TerragruntHCLProvider).prepWorkingDirs.func1.1()|github.com/infracost/infracost/internal/providers/terraform.(*TerragruntHCLProvider).prepWorkingDirs.func1.1()>

I have multiple terragrunt environments with the setup like -

├── nonlive
│   ├── stage
│   │   ├── account.hcl
│   │   ├── vpc
└── terragrunt.hcl

Any ideas on how to rectify? Terragrunt validate returns successful

@brief-ice-47661 looks like this error is coming from the internal terragrunt libraries. 1. Is there anything more in the stack trace/debug logs (

--log-level=debug

) that could help 2. Are you able to provide a reproducible project that we can use to replicate this issue?

Hey @little-author-61621 Thank you for the response These are the last few log lines for the debug output before showing the error in the first message

Thanks @brief-ice-47661, not seeing anything obvious there. Are you able to provide code that reproduces this issue?

@little-author-61621 Not at the moment, I can provide you with the tree with commands I used if that would be helpful?

I think we’ll need a full example to reproduce this since the error seems to be coming from the Terragrunt libraries we are using internally.

@little-author-61621 I have attached the entire debug report, there are a few errors such as "exec: no command", could this be the cause? I will see if I can get some reproducable code for you

Thanks

Hey @little-author-61621 Did you happen to find anything in the debug report?

Hi @brief-ice-47661, it could be the

exec: no command

stuff, but I don’t think I can get any further with this without a reproducible example.
