KeyError: 'edges'

Checking out terravision for the first time and running into the following issue with a simple Azure Resource Group Terraform file.

My environment: OS: MacOS Sonoma 14.4.1 terravision Version: 0.5 pyenv Version: 2.4.0 python3 Version: 3.10.14

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

[patrickmlvn]

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?

[patrickmlvn]

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:

error

``` > terravision draw --debug [sic] 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..

```hcl 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

```hcl resource "azurerm_resource_group" "this" { name = "sandbox-cus-rsg" location = "centralus" tags = { environment = "sandbox" } } ```
