bots - 涉及嵌入图像的 Discord.js 机器人错误

Question

因此，我编写了一个不和谐机器人，以根据命令从嵌入消息的文件夹中发送随机选择的 gif。在我开始尝试从 Heroku 托管机器人之前，它运行良好。现在该命令什么也不做，只是在日志中显示一个错误，比如“找不到文件扩展名”、“弃用错误”，或者刚刚，“未处理的承诺拒绝”。我的主要问题是我对编程很陌生，所以我不知道我的问题到底是什么，更不用说如何解决它了。

这是我在这个特定部分的当前代码：

   case '//command':
        const Embed = new MessageEmbed()
        var number = 43;
        var imageNumber = Math.floor (Math.random()*(number-1+1))+1

        Embed.setTitle("//message")
        Embed.setDescription("//message")
        Embed.attachFiles({files: ["./images/" + imageNumber + ".gif"]})
        Embed.setImage("attachment://" + imageNumber + ".gif")
        Embed.setColor(0x9B00C3)

        msg.channel.send(Embed)
        break;

编辑：根据要求，这是出现的错误消息：
