I am trying, when someone writes a message in guild A/B/C, the bot who is in for example 3 servers, to send me the message in the 4th server, sending them in different text channels named "guild A", "guild B" and " guild C ", not in the same ones...
I get the following error:
channel.send(msgLog)
TypeError: Cannot read property 'send' of undefined
And this is my code:
const msgLog = `[#${message.channel.name}]=[${message.author.username}#${message.author.discriminator}]=> ${message.content}` ```
client.guilds.cache.map(guild => server.channels.cache.find(channel => channel.name == guild.name)).forEach(channel =>
channel.send(msgLog)
);
The error means that channel is undefined, and you cannot any property (such as 'send') of undefined.
This means that server does not have a channel with the name guild.name for some guilds.
You could use filter to only include channels that are defined:
client.guilds.cache
.map(guild => server.channels.cache.find(channel => channel.name == guild.name))
.filter(channel => channel) // returns false if channel === undefined
.forEach(channel => channel.send(msgLog));
This is roughly equivalent to
client.guilds.cache.forEach(guild => {
const channel = server.channels.cache.find(channel => channel.name == guild.name));
if (channel) {
channel.send(msgLog);
}
});
