heroku 上的 Discord.JS 机器人 [重复]

Question

昨天我使用 Discord.JS 创建了一个 Discord 机器人，当我在本地使用我的机器人时它可以正常工作，但是在 Heroku 上托管它之后它不再工作并且机器人处于离线状态。 在 Heroku 日志中，我可以看到：

This error originated either by throwing inside of an async function without a catch block, or by rejecting a promise which was not handled with .catch(). To terminate the node process on unhandled promise rejection, use the CLI flag `--unhandled-rejections=strict` (see https://nodejs.org/api/cli.html#cli_unhandled_rejections_mode). (rejection id: 2)
2021-09-15T13:39:12.039451+00:00 app[worker.1]: (node:4) [DEP0018] DeprecationWarning: Unhandled promise rejections are deprecated. In the future, promise rejections that are not handled will terminate the Node.js process with a non-zero exit code.

我完全不知道该错误的原因是什么。 如果有人可以帮助我，我会很高兴
