Discord.js: The ChannelManager.fetch() method does not return an object of type Channel.

Hi!

I am testing discord.js to interact on my server with my bot.
When wanting to recover a channel and use the characteristics of typescript, I realized that the return type in the .fetch method of the ChannelManager object is wrong.
The official documentation indicates that it returns an object of type Channel, but it is not what really happens.

This error prevents us from declaring the type of object received and then accessing its properties.

The following type declaration returns a typescript error:

// Fetch a channel by its id
const channel: TextChannel = await this.discordClient.channels.fetch('CHANNEL_ID');

Changing the return type would fix this error?

Thanks!

Channel is the common ancestor of all types which can be fetched using that method. However tighter inference of types is not possible due to some quirks in the way the classes are written (which is in JS, not TS)

To use this with TS you'll need to force typecasting with as TextChannel or similar.
