Hi Jim,
I have layout.yaml defined as below. I don't see the jobs trigger by zuul in my env set up.
Review job is ok to run but it didn't trigger the next is approval. Could you help to point me why?

In layout.yaml:
Pipeline:
  - name: review^M
    description: Newly uploaded patchsets enter this pipeline to receive an initial +/-1 Verired vote from Jenkins.^M
    failure-message: Build Failed on pipeline check.^M
    manager: DependentPipelineManager^M
    precedence: low^M
    trigger:^M
      gerrit:^M
        - event: patchset-created^M
        - event: change-restored^M
        - event: comment-added^M
          comment_filter: recheck\scode^M
    success:^M
      gerrit:^M
        code-review: 1^M
    failure:^M
      gerrit:^M
        code-review: -1^M
      

  - name: approval^M
    description: Changes that have been approved by develpers are enqueued in order in this pipeline, and if they pass the
