Set autorole on specific guilds only - discord.js

Question

I'd like to auto set roles for new users when they join server X, problem is that this bot is on server Y as well, and server Y doesn't have the role.
client.on('guildMemberAdd', member => {
console.log('User ' + member.user.tag + ' has joined Steampunk.');
var role = member.guild.roles.find(x => x.name === "name");
member.addRole('247442955651121154');
})
I was hoping that I could do a simple check before applying the role, if user have joined server X, add the role, if else, do nothing. So far my attempts have failed.
Any input would be appreciated!

Answer 1

The original code is trying add a specific role you put in, and not the role you just looked up a line before that. There shouldn't be any issues with other servers the bot is in, because member.guild gives the guild of the member object, and since this member object is coming from a guildMemberAdd it means that member.guild will only return the guild that was just joined. The code in the edit has a lot of strange things going on, though.
The first issue I see is that in order to look through the channels in a guild, you have to use guild.channels.cache.find(), guild.channels.find() is old now and doesn't work in v12. Same goes for client.guild, guild.roles, etc. The part at the bottom of your edited code doesn't seem to make much sense at all. The code should get the roles of the newly joined guild (member.guild.roles.cache), look through them to find the role you want (you did this correctly with the .find()) and then apply the role to the member. Neither server nor role ever get used in your code, and guild.id is a property, not a method.
Let me know if you need help following these instructions, although it looks like you should be able to do it now. Always look at the discord.js docs first to check properties, methods, etc.

I ended up defining the guild in question by name, saved it as a const, and made a check for the specific guild.
If your bot is on several servers but you only want the greet/addRole on a specific one, all integrated into the message displayed on joining;
//Welcome message and autorole for specific server and channel.
client.on('guildMemberAdd', member => {
const = client.guilds.find(guild => guild.name === "Steampunk");
if (!guild) return;
const channel = member.guild.channels.find(ch => ch.name === "greetings");
if (!channel) return;
let botembed = new Discord.RichEmbed()
.setColor("#ff9900")
.setThumbnail(member.user.avatarURL)
.setDescription(`${member} Welcome to the Ark Steampunk Sponsored Mod Discord!\nPlease report all <#244843742568120321> and if u need any help view or ask your question in <#334492216292540417>.

.setTimestamp()
.setFooter("Steampunk Bot", client.user.avatarURL);
channel.send(botembed);
console.log('User ' + member.user.tag + ' has joined ' + member.guild.name + '.');
var role = member.guild.roles.find(x => x.name === "name");
member.addRole('247442955651121154');
});
