I want to make a pipeline in bitbucket for flask. Which can automatically deploy in ec2 instance.

I have tried below but it is troughing error of permission denied even i changed the permissions on remote server. And also cross checked the public keys on remote server and bitbucket.

  branches:
    main:
      - step:
          name: Deploy to Server
          script:
            - echo "Deploying to server"
            # Add the server's SSH key to the list of known hosts
            - pipe: atlassian/scp-deploy:1.5.0
              variables:
                USER: 'ubuntu'
                SERVER: 'my remote server ip'
                REMOTE_PATH: '.'
                LOCAL_PATH: '.'
                DEBUG: 'true'

And please add how to restart or start flask server from this pipeline.

Pipeline to transfer code on ec2 instance and restart the flask server
