I have this script to develop CI/CD pipeline using GitHub action. Pipeline's flow is like GitHub -> Docker Hub -> IBM Cloud Kubernetes. I'm facing this issue for 2-3 days while running kubernetes set image command. Tried many things but no luck. And I'm kind a new at this GitHub Actions and Kubernetes. My script;

on:
  push:
    branches:
      - master
jobs:

  build:

    runs-on: ubuntu-latest

    steps:

    - uses: actions/checkout@v2

    - name: Login to DockerHub
      run:  echo ${{ secrets.DOCKER_PASSWORD }} | docker login -u ${{ secrets.DOCKER_USERNAME }} --password-stdin

    - name: Check docker login status
      if: failure()
      run: echo Docker login process failed. Please check the GitHub secrets and your credentials.

      #    - name: Build the Docker image
      #      run:  docker build -t ${{ secrets.DOCKER_REPO }}:${GITHUB_SHA::8} .

      #    - name: Publish to Docker Hub
      #      run:  docker push ${{ secrets.DOCKER_USERNAME }}/nodedemoapp:${GITHUB_SHA::8}

    - name: Install IBM Cloud CLI
      run:  curl -sL https://ibm.biz/idt-installer | bash

    - name: Login to IBM Cloud
      run:  ibmcloud login -u ${{ secrets.IBMCLOUD_USER }} -p ${{ secrets.IBMCLOUD_PWD }} -r au-syd

    - name: Check IBM Cloud login status
      if: failure()
      run: echo IBM Cloud login process failed. Please check the GitHub secrets and your credentials.

    - name: Select Cloud Cluster
      run:  ibmcloud cs cluster-config <cluster-name>

    - name: Deploy to Cluster / Set Docker Image tag
      uses: steebchen/kubectl@master
      env:
              KUBE_CONFIG_DATA: ${{ secrets.KUBE_CONFIG_DATA }}
              DOCKER_REPO: ${{ secrets.DOCKER_REPO }}
      with:
              args: set image --record deployment/demo-nodeapp nodeapp=$DOCKER_REPO:dd317a15

              #    - name: Verify Deployment
              #      uses: steebchen/kubectl@master
              #      env:
              #              KUBE_CONFIG_DATA: ${{ secrets.KUBE_CONFIG_DATA }}
              #              DEPLOYMENT_NAME: ${{ secrets.DEPLOYMENT_NAME }}
              #      with:
              #              args: '"rollout status deployment/$DEPLOYMENT_NAME"'

And while executing it this is the error I'm facing;

Error in GitHub Action

Thanks in advance.
