Hello,
I wanted to try out the tool. I have got everything setup and all dependencies installed using vscode on a windows machine.
I am using following command to generate the diagram.
python terravision draw --source <path-to-my-terraform-code-folder>

I am getting the following error.

Planning failed. Terraform encountered an error while generating this plan.
