Github操作卡在“启动工作流运行”上

我已经为我的Express设置了GitHub工作流。一个月前的js RESTapi项目。那些日子我工作得很好。但现在,当我今天尝试运行同样的程序时,它会在屏幕上出现问题

正在启动工作流运行

# This workflow will do a clean install of node dependencies, build the source code and run tests across different versions of node
# For more information see: https://help.github.com/actions/language-and-framework-guides/using-nodejs-with-github-actions

name: DEV BUILD

on:
  push:
    branches: [ dev ]
  pull_request:
    branches: [ dev ]

jobs:
  build:

    runs-on: self-hosted 

    strategy:
      matrix:
        node-version: [ 14.x,15.x]
        # See supported Node.js release schedule at https://nodejs.org/en/about/releases/

    steps:
    - uses: actions/checkout@v2
    - name: Use Node.js ${{ matrix.node-version }}
      uses: actions/setup-node@v2
      with:
        node-version: ${{ matrix.node-version }}
    - run: rm package-lock.json
    - run: npm i
    - run: pm2 restart app.js

这个文件怎么了?有没有办法查看日志文件,以便我知道出了什么问题?

任何帮助! 提前感谢。=)
