IsJsonEncodable is not a function

Im pretty new in the discord bot community, so my error might be pretty stupid. So basically I am making a botstats command and the bot starts just fine but when I run the command it will crash and give this error (image), This is my code: ``ts import { SlashCommandBuilder } from "@discordjs/builders"; import { CommandInteraction, EmbedBuilder } from "discord.js"; import { SlashCommand } from "../types"; import { getThemeColor } from "../functions"; const command: SlashCommand = { command: new SlashCommandBuilder() .setName("stats bot") .setDescription("Shows bot statistics"), execute: async (interaction: CommandInteraction) => { const bot = interaction.client; const uptime = bot.uptime || 0; const guildsCount = bot.guilds.cache.size; const usersCount = bot.users.cache.size; const embed = new EmbedBuilder() .setColor(getThemeColor("text")) .setTitle("Bot Statistics") .addFields( { name: "Uptime", value: formatUptime(uptime) }, { name: "Servers", value: guildsCount.toString() }, { name: "Users", value: usersCount.toString() } ) .setTimestamp() .setFooter({ text: "Test123", iconURL: interaction.client.user?.avatarURL() || undefined }); await interaction.reply({ embeds: [embed] }); }, cooldown: 10 }; export default command; function formatUptime(uptime: number): string { const seconds = Math.floor((uptime / 1000) % 60); const minutes = Math.floor((uptime / (1000 * 60)) % 60); const hours = Math.floor((uptime / (1000 * 60 * 60)) % 24); const days = Math.floor(uptime / (1000 * 60 * 60 * 24)); return ${days}d ${hours}h ${minutes}m ${seconds}s`; }
