"Unsupported attribute; This object does not have an attribute named" : Issue with terragrunt init not populating state for a dependent module

[kami379]

Describe the bug

I am running terragrunt init for four modules. The first two modules execute successfully, and their respective state.tf files contain the expected resources and outputs.

However, the third module, which depends on the first and second modules, ends up with an empty state.tf (no resources, no outputs), even though there are many resources that should be created. However, this causes an error when creating the fourth module, and later during terragrunt plan and apply...

Why does the third module's state.tf remain empty after init, even though the resources are displayed in the plan and apply logs?

Steps To Reproduce

terragrunt run -all init

Expected behavior

The state file for the third module contains all resources and defined outputs, so the fourth module initializes successfully, and terragrunt plan and apply execute successfully
