Conversion of type '{ event: "GUILD_MEMBER_ADD"; data: { user: User; guild_id: string; id: string; nick: undefined; roles: string[]; joined_at: Date; deaf: boolean; mute: boolean; pending: boolean; bio: string; }; guild_id: string; }' to type 'GuildMemberAddEvent' may be a mistake because neither type sufficiently overlaps with the other. If this was intentional, convert the expression to 'unknown' first.
