Estoy creando un nuevo bot de discord para ayudarme a aprender discordjs y JS en general, pero sigo recibiendo el siguiente error HTTP y no puedo encontrar una manera de resolverlo. Usando discord.js versión 13.8.0

Ver mensaje de error:

 DiscordAPIError: 405: Method Not Allowed at RequestHandler.execute (C:\Users\Offic\Desktop\___\LearningBot\node_modules\discord.js\src\rest\RequestHandler.js:350:13) at processTicksAndRejections (node:internal/process/task_queues:96:5) at async RequestHandler.push (C:\Users\Offic\Desktop\___\LearningBot\node_modules\discord.js\src\rest\RequestHandler.js:51:14) at async ApplicationCommandPermissionsManager.set (C:\Users\Offic\Desktop\___\LearningBot\node_modules\discord.js\src\managers\ApplicationCommandPermissionsManager.js:186:18) at async C:\Users\Offic\Desktop\___\LearningBot\handlers\commands.js:66:12 { method: 'put', path: '/applications/986771474943709244/guilds/986441402735022140/commands/permissions', code: 0, httpStatus: 405, requestData: { json: [], files: [] }

El siguiente es el fragmento de código defectuoso:

 client.on("ready", async () => { const MainGuild = await client.guilds.cache.get(process.env.GUILDID); MainGuild.commands.set(commandsarray).then(async (command) => { const Roles = (commandname) => { const cmdperms = commandsarray.find((c) => c.name === commandname).permission; if(!cmdperms) return null; return MainGuild.roles.cache.filter((r) => r.permissions.has(cmdperms)); } const fullPermissions = command.reduce((accumulator, r) => { const roles = Roles(r.name); if(!roles) return accumulator; const permissions = roles.reduce((a, r) => { return [...a, {id: r.id, type: "ROLE", permission: true}] }, []); return [...accumulator, {id: r.id, permissions}] }, []); await MainGuild.commands.permissions.set({ fullPermissions }); }); });

La sección donde se presenta el error es:

 await MainGuild.commands.permissions.set({ fullPermissions });
