Hello all

I'm setting up a pipeline with following yml:

image: maven:3.6.1

pipelines:
  branches:
    staging:
      - step:
          name: Build
          caches:
            - maven
          script:
            - mvn clean package -Ptest -Dmaven.test.skip=true
          artifacts:
            - '/opt/atlassian/pipelines/agent/build/target/**'

      - step:
          name: Deploy
          #deployment: Test
          script:
            - pipe: atlassian/sftp-deploy:0.5.6
              variables:
                USER: $user
                PASSWORD: $password
                SERVER: $host
                REMOTE_PATH: $remote_path
                LOCAL_PATH: '/opt/atlassian/pipelines/agent/build/target/**'
                DEBUG: 'true'

The build steps runs without errors, but the "Deploy" step shows:

.... some more debug entries
