我正在尝试制作一个具有 Akinator 命令的 discord.js 机器人（我猜你知道那是什么） 我找到了 tutorial 的 aki-api 我做了它所说的一切，我得到了这个“简单”可修复的错误
TypeError: Cannot read property 'toLowerCase' of undefined
at regionURL (E:\Users\kazak\Documents\GitHub\Vixo\node_modules\aki-api\dist\functions\Request.js:90:63)
at Akinator.start (E:\Users\kazak\Documents\GitHub\Vixo\node_modules\aki-api\dist\Akinator.js:35:56)

at processTicksAndRejections (internal/process/task_queues.js:95:5)
我去了错误位置，发现了这一行 await aki.start()，但我不明白为什么它会把我带到那里
这是代码的其余部分，所以你们可以理解......我会在错误发送给我的地方添加评论
