我正在尝试通过Heroku创建一个Discord机器人。我终于设法让DYNO机器人出现了，但是现在当我使用命令打开程序时，出现了应用程序错误。查看日志，发现bash: command_to_run_your_worker: command not found似乎是造成我大部分问题的原因。因为我有worker: command_to_run_your_worker，所以不应该这样，所以我认为我把它放在错误的位置。有什么建议么？这是日志的一部分。
我已经搜索了所有wiki，但没有提及有关运行工作程序的命令的任何信息。

我真的只是希望让Discord机器人正常工作。在这一点上，我有些侧翼，需要一些步骤。
