Discord Bot doesnt send message when user reacts

Question

So my bot doesn't send a message when the user reacts even though he should, and then there are the errors... btw I put so many.catch error in the code because of the promise rejection error

client.on("guildMemberAdd", member => {
    try {
        member.send(`Hello ${member}, welcome to the PotatoHost Server! 
I want to help you and so my question is: Do you want to buy a server or do you need more informations first? \n
A: I want to buy a server
B: I need more informations first \n
Please react to this message with A or B.`)
        .catch(err => console.log('err1'))
        .then(function (message) {
            message.react("🇦")
            .catch(err => console.log(err));
            message.react("🇧")
            .catch(err => console.log(err));
            message.awaitReactions((reaction, user) => user.id == message.author.id && (reaction.emoji.name == '🇦' || reaction.emoji.name == '🇧'),
                { max: 1})
                .catch(err => console.log(err))
                .then(collected => {
                    if (collected.first().emoji.name == '🇦') {
                        message.send('Ok, so you want to buy a server. Let me recommend you to visit <#699374469977735208>.')
                        .catch(err => console.log(err));
                    }
                    else
                      message.send('Ok, so you need more informations first. Let me recommend you to visit <#699374469977735208>.')
                      .catch(err => console.log(err));
                })
        });
    }catch (err) {
         console.log(err)
    }
})

Here are the errors that i dont know how to fix:

(node:31944) UnhandledPromiseRejectionWarning: TypeError: message.send is not a function

There is no such thing as message.send() you need to replace that with message.channel.send()

You have been asking questions about little things like this for a bit, you need to read the documentation: https://discord.js.org/#/docs/main/stable/general/welcome
