@full-planet-90153 for env variables you’ll need to specify the value for Infracost to know it. You can do this by either:
1. Setting it globally for the GitHub integration: Org Settings > Integrations > GitHub > Next > Do you need additional environment variables?
2. Adding a config file for the repo that contains the env value: Visibility > Repos > repo > Settings > Config file. And then adding a config file that looks like this:
version: 0.1
projects:
- path: .
env:
TF_VAR_instance: my-instance
