为什么我的频道消息发送代码不起作用？

Question

I am trying to send a message at a specific hour on my discord bot but my code isn't working. I get a "Cannot read property 'send' of undefined" error. Send part isn't working, i don't know why. I used the same send code elsewhere but it works there. The code i am using is like this. It was saying message is unidentified before i wrote 'message' in function so i solved it like that. I am a beginner so take it easy on me, Please help, thanks!

    var schedule = require('node-schedule');

var scheduleFunction = schedule.scheduleJob('00 19 * * *', function(message) {
    message.channel.send('test!');
});

It seems message doesn't refer to a specific message and is thus coming back undefined. Instead, use

var channel = <ID of channel you want the message to be sent to>
client.channels.cache.get(channel).send('test!'):
