GitHub Actions工作流推送失败（权限拒绝）求助

我几天前创建了首个GitHub Actions工作流，用于自动化Next.js应用的若干脚本，但始终无法正常运行。尝试过多种修改来解决权限问题均无效，以下是我的automated-data-updates.yml文件：

name: Automated Data Updates

    - cron: "0 14 * * 5"

    - cron: "0 7 * * 2"
    # Fetch players - Fridays at 15:00 UTC
    - cron: "0 15 * * 5"
    # Fetch players - Mondays at 15:00 UTC
    - cron: "0 15 * * 1"
    # Fetch players - Wednesdays at 15:00 UTC

补充信息：

• PAT处于活跃状态，未过期
• PAT由仓库所有者账号创建，具备推送权限
• 无分支保护规则
• PAT在本地可正常执行推送操作

工作流运行时，推送步骤总会失败，报错信息如下：

remote: Permission to user/repo.git denied to github-actions[bot].
fatal: unable to access 'https://github.com/user/repo/': The requested URL returned error: 403
Error: Process completed with exit code 128.
