我目前正在js中创建一个discord机器人，但我遇到了麻烦，但我不知道它是从哪里来的，有人能帮我吗？

bot.on('presenceUpdate', (oldPresence, newPresence) => {
  const role = newPresence.guild.roles.cache.get("863104096377503754");
  const member = newPresence.member
  const activities = member.user.presence.activities[0];

  if(newPresence.activities[0].state === "hello") {
    return newPresence.member.roles.add(role).catch((e) => console.log(e));
  }
  if(!newPresence.activities[0].state === "hello") {
    return newPresence.member.roles.remove(role).catch((e) => console.log(e));
  }
})

我有这个错误
