node.js - 无法读取未定义错误 aki-api 的属性“toLowerCase”

Question

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）

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 Object.execute (E:\Users\kazak\Documents\GitHub\Vixo\commands\fun\aki.js:36:16)
    at Object.execute (E:\Users\kazak\Documents\GitHub\Vixo\events\message.js:202:12)
    at processTicksAndRejections (internal/process/task_queues.js:95:5)

我去了错误位置，我发现了这一行await aki.start()，但我不明白为什么它会把我带到这里是其余的代码，所以你们都可以理解。我会在错误发送给我的地方添加注释

            }
        }
        catch(err) {
            console.log(err);
            return message.channel.send(`Oh no an error occured: \`${err.message}\` Try again`);
        }

    },
};

还有一个文件，但我不会显示它，因为它会在之后执行await aki.start()
