I am able to create AKS cluster using terraform and git workflow. But unable to destroy it from git hub workflow.

I always get message (No changes. No objects need to be destroyed) even the resources are present on portal and workflow completed. I used to delete manually from azure portal.

Can someone please guide me ?
Here is the workflow which I am using

name: abc

on:
workflow_dispatch:
inputs:
environment:
description: “Select the environment. Allowed values are ‘DEV'”
required: true
type: choice
options:
– DEV

  tf-action:
    description: 'Select either to "create" or "destroy" the infrastructure'
    required: true
    type: choice
    options:
      - create
      - destroy
