guild.fetchOwner() is returning a collection of guild members

Which package is this bug report for?

discord.js

Issue description

Using Discord 13.6.0 I am trying to get the id of the guild, is not working for me.

Trying guild.ownerId returns undefined, but I was then directed to try guild.fetchOwner(), but this returns a list of members of the guild instead of a GuildMember.

Looking at the Discord source code suggests that if guild.ownerId is undefined, this will return all the members of the guild:

``js fetchOwner(options) { return this.members.fetch({ …options, user: this.ownerId }); }

### Code sample

```typescript
To get the guild:


  async getGuild (guildId?: string) {
    const client = await this.getClient();
    const guildResolvable = client.guilds.resolveId(guildId || this.guildId);

    const guild = client.guilds.resolve(guildResolvable);
    if (!guild) {
      throw new Error('Unable to access guild');
    }
    return guild;
  }


This returns a guild with `ownerId` being `undefined, but then calling `guild.fetchOwner()` returns a collection of form `Collection(11) [Map] { ... }`.

Yes, I just noticed through extra experimenting, though it wasn’t clear from the documentation:

https://discord.js.org/#/docs/discord.js/stable/class/Guild?scrollTo=fetchOwner

Also, would it be possible to have code provide clarity on this, such as:

fetchOwner(options) {
    if (!this.ownerId) {
       throw new MissingIntent('GUILDS intent is required to use this');
    }
    return this.members.fetch({ ...options, user: this.ownerId });
}

Though, not sure if that fits with the API’s philosophy?

Although I don’t agree with this particular error message, I do think this method should reject if guild.ownerId isn’t defined. It’s designed to fetch a single GuildMember. If it cannot do so, it should reject.

The current behaviour where in an edge case it can return a Collection of GuildMembers is not the expected result and should be considered a bug.
