Thanks for the bug report. Can you confirm if this still exists with the latest release pushed just now?

You're welcome. Upgraded to terravision 0.6 and re-ran the command but still running into an issue, looks like the debug is slightly different now:

It's very peculiar that your tf graph output doesn't have any edges? I made some modification to check for the edges. Please try again and if it doesn't work can you share your Terraform source with me so I can try to reproduce the error?

Thanks for the update. Pulled the latest changes in main and I am no longer receiving the edges error. However, I do receive this error:

Decoding plan..


Analysing plan..


Converting TF Graph Connections..  (this may take a while)


ERROR: No AWS, Azure or Google resources will be created with current plan. Exiting.

It could still be a user error on my end, but I tried with just a simple Azure Resource Group creation, as well as a Resource Group, VNET, and NSG. I also tried with a clean environment (removed .terraform/ and .terraform.lock.hcl) with no change.

Just to rule out how/where I was running terravision, all of my attempts have been from within the directory that contains my terraform code. I also tried running from the terravision directory and supplying the --source parameter with no change in the error.

Below, you can see that terraform plan that terravision is executing does see changes to apply:

Generating Terraform Plan..

Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:
  + create

Terraform will perform the following actions:

  # azurerm_resource_group.this will be created
  + resource "azurerm_resource_group" "this" {
      + id       = (known after apply)
      + location = "centralus"
      + name     = "sandbox-cus-rsg"
      + tags     = {
          + "environment" = "sandbox"
        }
    }

Plan: 1 to add, 0 to change, 0 to destroy.

If it would still be helpful, I've included the terraform code below (if you need the provider, or any other info, let me know).

main.tf

resource "azurerm_resource_group" "this" { 
  name     = "sandbox-cus-rsg"
  location = "centralus"

  tags = {
    environment = "sandbox"
  }
}
