“UnhandledPromiseRejectionWarning：DiscordAPIError：缺少权限”

Question

我正在尝试编写一个机器人，当用户加入服务器时，它会为他添加角色“Banda canina”，我试图给他一个管理员角色，但它继续给出这个错误。这是代码

bot.on('guildMemberAdd', member => {
    let wChannel = member.guild.channels.cache.find(channel => channel.name === botConfig.canale_benvenuto);
    if(!wChannel) return console.log('Canale di log non valido');

    let wRole = member.guild.roles.cache.find(role => role.name === botConfig.ruolo_base);
    if(!wRole) return console.log('Impossibile trovare il ruolo base');

    wChannel.send(`${member.user.username}#${member.user.discriminator} è entrato nel server`);
    member.roles.add(wRole);
});

我在另一台测试服务器上尝试了该机器人，它可以工作，但在主服务器上却不行。这是完整的错误：

您的机器人应该有权管理该服务器中的角色，并且还应该拥有它赋予新成员的角色。
