DiscordJs cascade of awaitMessages - discord.js

Question

I'm new to the discordjs package and I've been digging around but for the last 2 days I'm stuck at this.
What I'm trying to achieve is "questionnaire" that will guide the user through some questions. An example would be:
User types: !askOrder
Q: Do you want red wine or white wine?
A: white wine
Q: You want white wine. Do you prefer a verdejo or a rueda?
A: rueda
Q: A rueda it's. Do you want it at room temperature or chill?
A: room temperature.
What I've is:
msg.author.send('Do you want red wine or white wine?');
msg.author.send(WineText)
.then((systemMsg) => {
systemMsg.channel.awaitMessages(response => response.content, {
max: 1,
time: 5000,
errors: ['time'],
}).then((collected) => {
systemMsg.channel.send(`You want ${collected.first().content}. Do you prefer a verdejo or a rueda?`);
collected.channel.awaitMessages(response => response.content, {
max: 1,
time: 10000
});
})then((collected2) => {
systemMsg.channel.send(`A ${collected2.first().content} it's. Do you want it at room temperature or chill? `);
}).catch((err) => {
return;
});
But it simply stops after it asks the second questions, not capturing/collecting the second answer. What is it that Im doing wrong?
Thanks a lot for your answers!

Answer 1

What I'd do is put all of the questions (and answers) in an array, wrap those statements in a function, and loop them over an iteration like this:
let i = 0; let questions = ['Q1', 'Q2'];
function askQuestion() {
const filter = m => m.author.id == message.author.id;
message.channel.send(questions[i]).then(() => {
message.channel.awaitMessages(filter, { max: 1, time: 120000, errors: ['time'] })
.then(async collected => {
//do stuff
message.channel.send(`answer was ${collected.first().content}`);
i++; //increase iteration
if (i === questions.length) return;
else askQuestion();
})
.catch(collected => {
//timed out
});
});
}
askQuestion();
It helps clean your code a little bit. You can change them as you see fit.
I made a bot that ask questions just like this, you can view the code here

Answer 2

You structured your awaitMessages events wrong:
msg.author.send('Do you want red wine or white wine?');
msg.author.send(WineText)
.then((systemMsg) => {
systemMsg.channel.awaitMessages(response => response.content, {
max: 1,
time: 5000,
errors: ['time']
}).then((collected) => {
systemMsg.channel.send(`You want ${collected.first().content}. Do you prefer a verdejo or a rueda?`);
collected.first().channel.awaitMessages(response => response.content, {
max: 1,
time: 10000
}).then((collected2) => {
systemMsg.channel.send(`A ${collected2.first().content} it's. Do you want it at room temperature or chill? `);
}).catch((err) => {
return;
});
});
});
There were 2 crucial errors you made:
(1) You sent a message to collected.channel. However, collected is a collection of messages, and doesn't have a channel property. To send it to the channel, just do collected.first().channel, since collected.first() is a message.
(2) You were missing two })s at the end of your code, because of the thens that you included and never closed.
