'invalid memory address or nil pointer dereference' against local plan

[fernandino143]

Are there any tf version constraints, perhaps? I've performed the terraform plan to generate the expecte file and executed rover.

Terraform v0.12.31

$ terraform plan -out plan_new.tfstate
...
This plan was saved to: plan_new.tfstate

To perform exactly these actions, run the following command to apply:
    terraform apply "plan_new.tfstate"
$ ~/rover_v0.3.3 -tfPath "/opt/homebrew/bin/terraform" -planPath "plan_new.tfstate"

The module is quite big, but nothing stupendous - 85K in size after terraform plan. It does make use of "stack.auto.tfvars.json" for variables, though. Could that be it?:

I also tried the json format after transofrming it to json (which render fine with jq), but that fails immediately:

$ ~/rover_v0.3.3 -tfPath "/opt/homebrew/bin/terraform" -planJSONPath "plan.json"

Worth mentioning that the tests from the examples provided were successful and my team and I are quite excited to use this tool on our own modules. Please advise.
