尝试分配角色时，我不断收到错误消息

Question

I have a small piece of code that reads from a mongodb database and give them the role in the database

The command requires the user to tag the person they wish to update, what am i doing wrong?

msg.mentions.members.first().addRole(msg.guild.roles.find(r => r.name === result[0].MainRank));

This is the error:

 TypeError: msg.guild.roles.find is not a function

Answer 1

You now have to use msg.guild.roles.cache.find , since v12 uses Managers.
