Hi InfraCost Team, Currently we are exploring product for our use cases. I have gone through setup process and able to generate cost via

infracost breakdown --path .

but not able to print message in Github PR comment although I do have this

infracost-base.json

file and also followed step number 4 per https://github.com/infracost/actions/. Can someone please help?

Hi Harish, do you have any log output you can share? Also it can be helpful to see the contents of your action.yml file.

you mean infracost.yml file?

yes

I just copy pasted as it is per your Git

# The GitHub Actions docs (<https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#on>)
# describe other options for 'on', 'pull_request' is a good default.
on: [pull_request]
env:
  # If you use private modules you'll need this env variable to use
  # the same ssh-agent socket value across all jobs & steps.
  SSH_AUTH_SOCK: /tmp/ssh_agent.sock

    env:

    steps:
