回答1:

GuildMember.roles returns an object of type GuildMemberRoleManager. To get the roles from this you want to use GuildMemberRoleManager.cache. This returns an object of type Collection<Snowflake, Role>. Once you have that, you can use Collection.find(fn, [thisArg]). BUT, in your specific case, you'd want to use Collection.some(fn, [thisArg]). The some method checks if a specific item exists based on a function.

Your code would instead look like this:

if(!message.member.roles.cache.some(r => r.name === "OWNER")) {
    //your code here
}
