I'm trying to fetch the bot's permissions to check if the command will be able to run. I have the following code:

let botid = "idbot"
let bot = client.users.cache.get(botid)
if (!bot.permissions.has("ADMINISTRATOR")) 
  return message.channel.send("Para mim poder liberar a função de registro eu preciso da permissão **Administrador**, por favor peça para algum **Staff** do servidor configurar, Obrigado.")

I receive the following error:

if (!bot.permissions.has("ADMINISTRATOR"))
                    ^
TypeError: Cannot read properties of undefined (reading 'has')

CodePudding user response：

Because bot as you defined it is just a User, meaning it just has informations like it's tag, username, servers it is in etc.. what you want is a GuildMember, it's the same person but on a specific server, it has roles, a hoist color and permissions which is what you're searching for :

let bot = message.guild.me; // The bot's GuildMember object
if (!bot.permissions.has("ADMINISTRATOR")) return message.reply('I am not an admin!')

CodePudding user response：

bot is a User and Users don't have permissions, only GuildMembers do. For this, you'll need to grab the Guild (either by getting by its ID, or just using message.guild). guild#me will be your bot as a GuildMember of that guild.

You could also just use the fetch method on guild.members. Anyway, you'll need a guild to check your bot's permissions.

let botid = 'idbot';
let guild = client.guilds.cache.get('GUILD_ID');
// OR get it from the message
let { guild } = message;

let bot = guild.me;
// OR fetch it from members
let bot = await guild.members.fetch(botid);

if (!bot.permissions.has('ADMINISTRATOR'))
  return message.channel.send(
    'Para mim poder liberar a função de registro eu preciso da permissão **Administrador**, por favor peça para algum **Staff** do servidor configurar, Obrigado.',
  );
