You need to provide URL information while making a request, check to see that correct URL is getting assigned to your webhook variable, i.e
您需要在发出请求时提供 URL 信息，检查是否已将正确的 URL 分配给您的 webhook 变量，即
var webhook = process.env.DISCORD_WEBHOOK; //webhook should be assigned a valid URL for example: 'https://stackoverflow.com/'
var webhook = process.env.DISCORD_WEBHOOK; //webhook 应该被分配一个有效的 URL，例如：' https://stackoverflow.com/'
try console.log(webhook);
试试 console.log(webhook);
to find out URL for which you are making a request.
找出您要请求的 URL。

Object request has parameter uri not url. https://github.com/request/request#multipartrelated
对象请求具有参数 uri 而不是 url。 https://github.com/request/request#multipartrelated
request({
method: 'POST',
uri: webhook,
json: {
"content": req.body.msg,
"username": "Potato"
}
});
