Question

因此，我是discord.js的新手，我正在尝试编写一个discord机器人。我正在使用snekfetch从以下URL检索数据：https://crystalmathlabs.com/tracker/api.php?type=comprankings&competition=19326

它可以工作，但有时会出现以下错误：

//first error from first command run        
(node:17512) UnhandledPromiseRejectionWarning: Error: 500 Internal Server Error
        at _response.transport.request.then (C:\Users\Alex\Downloads\discord-bot\node_modules\snekfetch\src\index.js:193:21)
        at process._tickCallback (internal/process/next_tick.js:68:7)
    (node:17512) UnhandledPromiseRejectionWarning: Unhandled promise rejection. 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(). (rejection id: 2)

//second error from the first command run a second time

//command run a third time, and it works

有人知道为什么有时会发生吗？

注意：代码运行后，我没有包括完整的输出，只是前几行

编辑：

发现错误并打印后，我收到此消息：

UnhandledPromiseRejectionWarning随机发生
