Inframap execution given a blank image for Terraform #236

Hello,

I have been testing inframap with the repo module-magento and the graphs are created correctly using

inframap generate ./terraform/module-magento/ | dot -Tpng > inframap.png

However, I try one of my repos that is using one of the latest terraform versions and it doesn't fail the execution, but the image that is generated is just a white blank square. Did you see this behaviour before? I believe it may be a compatibility with the terraform version?

The folder I point to, it contains terraform files as the magento has also which I don't understand if they are with similar structure, perhaps is there any correlation with versions or is there something else?

Thank you in advance,
GCM
