Crash in terraform console trying to access module variables #37352
Description
Terraform Version
terraform -version
Terraform v1.12.2
on darwin_arm64
+ provider registry.terraform.io/hashicorp/aws v6.3.0Terraform Configuration Files
Sorry, I can't share repository at least publicly, but could share privately
I can't really figure out what is causing this crash - apart that that I try to access module.subnet in console. Apply works fine though.
Debug Output
> module.subnet
