为什么我的 bitbucket-pipelines.yml 对于拉取请求脚本无效

Question

我有一个用于我正在处理的项目的 bitbucket pipeline yaml 文件。当它设置为在推送上运行时，我让它运行良好，但由于我将其切换为在拉取请求上运行，我收到了无效的 yml 错误。

我找到了如何配置文件的描述：https://confluence.atlassian.com/bitbucket/configure-bitbucket-pipelines-yml-792298910.html

在验证器中，我在第一步收到一个错误，提示Expected a string but found a mapping.

当我通过拉取请求运行它时，出现以下错误：

Configuration error
There is an error in your bitbucket-pipelines.yml at [pipelines > pull-requests]. 
To be precise: This section should be a map (it is currently defined as a list).

我不确定如何修复它，因为它似乎与示例相匹配。

下面是我的 yml 文件

pipelines:
  pull-requests:
    - step: 
        name: Push repo to CodeCommit
        script:
          - echo $CodeCommitKey > ~/.ssh/codecommit_rsa.tmp
          - base64 -di ~/.ssh/codecommit_rsa.tmp > ~/.ssh/codecommit_rsa
          - chmod 400 ~/.ssh/codecommit_rsa
          - echo $CodeCommitConfig > ~/.ssh/config.tmp
          - base64 -di ~/.ssh/config.tmp > ~/.ssh/config
          - set +e
          - ssh -o StrictHostKeyChecking=no $CodeCommitHost
          - set -e
          - git remote add codecommit ssh://$CodeCommitRepo
          - git push codecommit $BITBUCKET_BRANCH
    - step:
        name: Test and Build
        caches:
          - node
        script: 
          - npm install --no-package-lock
          - npm run test
    - step:
        name: Deploy Serverless
        script:
          - npm i serverless -g
          - npm run deploy

原来我以为只是一条评论，仔细一看却是文件的必要组成部分。只要确保正确缩进（空格）即可。

pipelines:
  pull-requests:
    '**':
      - step: 
          name: Push repo to CodeCommit
          script:
            - echo $CodeCommitKey > ~/.ssh/codecommit_rsa.tmp
            - base64 -di ~/.ssh/codecommit_rsa.tmp > ~/.ssh/codecommit_rsa
            - chmod 400 ~/.ssh/codecommit_rsa
            - echo $CodeCommitConfig > ~/.ssh/config.tmp
            - base64 -di ~/.ssh/config.tmp > ~/.ssh/config
            - set +e
            - ssh -o StrictHostKeyChecking=no $CodeCommitHost
            - set -e
            - git remote add codecommit ssh://$CodeCommitRepo
            - git push codecommit $BITBUCKET_BRANCH
      - step:
