How to write a role to a variable?
Tried:

let role = member.guild.roles.find(r => r.name = "Имя роли");
member.addRole(role)

But it gave an error. How to do?

Answer 1

member.addRole(role.id); - discord.js v11 
member.roles.add(role.id); - discord.js v12

Answer 2

you write the variable incorrectly, you simply didn’t transfer member.addRole(role)
read this , then try to run the code again. You can also try using a function
instead of a variable . if nothing from this list helped you, please write a comment under my answer with the error code.
