(Discord.JS) - Reaction Role error: "Cannot Read Property "roles" of Undefined"

Question

I am trying to make a "Reaction Role" command so that members can receive certain positions. Currently, I use this code:

client.on('raw', async dados => {
    if (dados.t !== "MESSAGE_REACTION_ADD" && dados.t !== "MESSAGE_REACTION_REMOVE") return
    if (dados.d.message_id != "780169693406429235") return

    let servidor = client.guilds.cache.get("774274642520965180")
    let membro = servidor.members.cache.get(dados.d.user_id);

    let cafet = servidor.roles.cache.get("<@&780176147681378335>"),
        inkei = servidor.roles.cache.get("<@&780175676380414002>"),
        mokuzai = servidor.roles.cache.get("<@&780175676380414002>");
    if(dados.t === "MESSAGE_REACTION_ADD") {
        if (dados.d.emoji.id === "774669881996083220") {
            if (membro.roles.cache.has(cafet)) return
            membro.roles.add(cafet);
        } else if (dados.d.emoji.id === "775031385542885406") {
            if (membro.roles.cache.has(inkei)) return
            membro.roles.add(inkei);
        } else if (dados.d.emoji.id === "774665913559023738") {
            if (membro.roles.cache.has(mokuzai)) return
            membro.roles.add(mokuzai);
        }
    }
})

However, this error following is returning to me on the console:

If anyone can help me, I’ll be immensely grateful!!!
