如何使 pr assignees 成为合适的环境变量？

Question

我正在执行 github 操作，在合并拉取请求时通过添加 PR 受让人的名称来编辑 README。我尝试设置一个环境变量以在我的 python 代码中使用，其值为 ${{github.event.pull_request.assignees}} 但是当运行一个示例 PR 合并时我收到以下错误：

Error: The template is not valid. 
.github/workflows/main.yml (Line: 32, Col: 22): A sequence was not expected

这是我当前的代码：

name: READMEUPDATER

on:
  pull_request:
    types: [ closed ]
    branches: [ main ]

jobs:

  update:

    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v2
        with:
          fetch-depth: 0

      - name: Edit the README.md
        if: |
            github.event.pull_request.merged == true
            && contains(github.event.pull_request.labels.*.name, 'workshop')
        run: |
              python ./scripts/updater.py
              git add README.md
              git commit -m "Auto update to README.md"
              git fetch origin master
              git push origin HEAD:master
        env:
          repo: ${{github.event.pull_request.base.repo.name}}
          assignees: ${{github.event.pull_request.assignees}}

我确实设法解决了它，问题是它将它解析为列表而不是分配给受让人变量的字符串，所以我只使用了这个：${{toJson(github.event.pull_request.assigness)}}。它将列表序列化为 json 字符串。而且提交部分还缺少 git config user.name "xxx".
