这几天我一直在努力解决这个问题。我有一个使用 Slack/Bolt 和内置 Express Server 进行开发的 Slack 应用程序。在开发过程中，我可以成功完成安装过程，完成后返回用户凭据（身份验证令牌、teamId 等）并将我重定向到我的成功页面。此外，我的斜杠命令按预期工作。
但是，在生产中，斜杠命令和安装过程都不起作用。斜杠命令在 Slack 中返回“dispatch_failed”错误，并在我的日志中返回以下验证错误：
开发中的安装过程从我的登录页面开始，该页面带有一个添加到松弛按钮，该按钮将我带到我授权所需范围的松弛页面。提交此表单是我的应用程序因 503 错误而超时的地方。我可以在 URL 中看到“代码”，但它没有被处理。在拆开应用程序以尝试不同的身份验证方法之前，我希望有人能找出我哪里出错了。
重要的是身份验证令牌。在开发中，我在声明 app 时声明了我的 xbot 令牌。我将其删除以进行生产，并从事件侦听器（斜杠命令等）的上下文变量中传递机器人令牌。这就是我从文档中理解该过程的方式，但可能是错误的......
