API必须返回少于400个字符

Question

我在HTML中创建了这个Javascript，我的朋友已经托管了它。它完美无缺，所以我假设它与代码无关：

var deaths = [
    "with a potato.",
    "by using a truck and running them over.",
    "with a gun, bang bang.",
    "by stuffing a mouldy lemon in their mouth.",
    "by throwing multiple knives at them.",
    "by throwing them off a building onto a cactus.",
    "by tying them up and forgetting about them.",
    "by using mind control and making them walk into lava."
    //"",
    //"",
    //"",
    //"",
    //"",
    //"",
    //"",
    //"",
    //"",
    //"",
    //"",
    //"",
    //"",
    //"",
];
var death = deaths[Math.floor(Math.random() * deaths.length)];
document.write(death)

我正在为nightbot制作一个命令，一个用于抽搐电视的机器人，并且在命令中它从上面的javascipt制作的网页中提取文本。我在命令中使用此$(customapi URL)，其中网址为URL，但是当命令运行时，它返回'[API必须返回少于400个字符]'。
