To run AWS Launch template CLI command in CI/CD pipeline

Hi AWS, I am trying to create an EC2 launch template using GitHub Actions and here is the code for the same:

name: Deploying a CI/CD for Amazon EC2 AMI

on:
  workflow_dispatch:
  push:
    branches: [ "master" ]
  pull_request:
    branches: [ "master" ]



jobs:

      deploy:
        runs-on: [ self-hosted, Windows, X64 ]
        timeout-minutes: 10
        defaults:
          run:
           shell: cmd
        steps:
         - name: Set AWS credentials
           uses: aws-actions/configure-aws-credentials@v1
           with:
             aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY }}
             aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
             aws-region: ${{ secrets.AWS_REGION }}

         - name: Create the AMI for the EC2 instance
           shell: powershell
           run: |
             $instance_id = Invoke-RestMethod -Uri http://169.254.169.254/latest/meta-data/instance-id

             $ami_id=(aws ec2 create-image --instance-id $instance_id --name "$ami_name" --tag-specifications "ResourceType=image,Tags=[{Key=Name,Value=$ami_name}]" --no-reboot --output text).ImageId
             echo "AMI_ID=$ami_id" >> $GITHUB_ENV

but while the pipeline is triggered it is throwing an error:

Can you please help me fixing this small issue? FYI the GitHub self-hosted runner is configured on an Amazon EC2 Windows machine.

Thanks
