"Send" does not exist on type "channel"

Hi. Trying to make a discord bot that will send a message to a specific channel on startup. I try the method of caching the channel and then sending the message. An error is thrown saying "Send" does not exist on type "channel".

const channel = client.channels.cache.get('1076251641625456700');
channel.send("Hi");

const channel = client.channels.cache.get('1076251641625456700');
channel.send("Hi");

Any thoughts why?

Solution:

Channel might net be a text based channel. Use channel.isTextBased() to ensure that it is before trying to send a message

chpsterzOP•2y ago

it is

Ben•2y ago

You may know that it is but the code doesnt. You still need to preform the check in the code.

Two things. First, remove the casting to a TextChannel because you cant be sure its a text channel. Second, channel is not a TextChannel, its undefined.

chpsterzOP•2y ago

yes so how do I make it not undefined and make it send a message?

Ben•2y ago

Well, are you sure that the id your using is correct? If so, it probably is not cached so you will need to fetch it with client.channels.fetch(...)

chpsterzOP•2y ago

yes that worked alrighty thank you very much.

const channel =  await client.channels.fetch("1076251641625456700");
        if(channel?.isTextBased() ) {
            channel.send("Hello World!")
        }

const channel =  await client.channels.fetch("1076251641625456700");
        if(channel?.isTextBased() ) {
            channel.send("Hello World!")
        }

Fetch the channel, make sure it is text based.

Wrong solution, see <#769862166131245066> in the DiscordJS server. Use isStageChannel function from @sapphire/discord.js-utilities and update to the latest sapphire framework as announced in #Announcements Specifically !isStageChannel(channel)

Ben•2y ago

oop. I didn't see the djs anouncment. But why would you use isStageChannel instead of isTextBased? Wouldnt !isStageChannel(channel) return true for categries & voice channels?

Krish•2y ago

You can send messages in VC

Ben•2y ago

Right I forgot they had text channels now. But you still cant send messages in a category channel Also I dont think .send exists on forum channels but I could be wrong about that

Krish•2y ago

Favna could answer

Favna•2y ago

because stage channels are also text channels so isTextChannel doesn't exclude stage channel stage channels can have messages now as of like last week or so which is why the change was made to discord-api-types to begin with

Ben•2y ago

So stage channels can now have text channels once djs updates to support it but checking !isStageChannel still assumes that you can send a message to a category which I'm pretty sure you cant.

Favna•2y ago

stage channels can now have messages and therefore they are text channels because the definition of a text channel is "can have messages"

Ben•2y ago

Right so then why would you check if a channel is not a stage channel before sending a message to it then?

Favna•2y ago

because at least for now DJS doesnt support sending a message to a stage channel until an update rolls out anyway yes you should do

if (!isTextChannel(channel) || isStageChannel(channel) {
  return;
}

// do other stuff

if (!isTextChannel(channel) || isStageChannel(channel) {
  return;
}

// do other stuff

for now

Ben•2y ago

Right so you would need to do that check in addition to the isTextBased. If you just did the stage check then you could end up sending to a category Yep I thought you were saying to just do the stage check, not both.
