Path Variables in terraform commands is not substiting the correct variable ( path: ${CIRCLE_BRANCH} ) #62

I am trying to use this orb for terraform CircleCI Developer Hub - circleci/terraform.

If we are adding the path as variable the orb fails

Path does not exist: ${CIRCLE_BRANCH}

The code which I am using is

version: 2.1
orbs:
  terraform: circleci/terraform@3.0.1

jobs:
  terraforming:
    executor: terraform/default
    steps:
      - checkout
      - terraform/init:
          path: ${CIRCLE_BRANCH}

Can anyone suggest the solution for the same.
