await payload.member.add_roles(role) でいけるのですが、消すほうは、

            member = guild.get_member(payload.user_id)
            await member.remove_roles(role)

という感じでいったんmemberを取得する必要があります。

リアクションが付けられた場合はpayloadの中にmemberが入ってくるのですが、リアクションが消されたときはmemberが存在しないためです。

[supleiades]

memberオブジェクトが取得できていないため、botという属性が存在しないと言われている

dmにメッセージを送信する処理（自己紹介）でこのエラーが発生しているようだ on_raw_reaction_addはギルド内もBOTのDMにも反応するが、今回エラーを起こしたコードはdmのオブジェクトに対応していないためエラーが発生していた

対応策

・メッセージのタイプがDMならreturnする処理を一番最初に追加する ・対象コードを確認しつつ、dmのメッセージに反応する必要がないかを確認した上でdmに反応しないように修正する

[supleiades]

ちなみに、dmのpayloadの中身

[DEBUG] (payload) <RawReactionActionEvent message_id=889316416149401680 user_id=618077392686153742 channel_id=754845237020590090 guild_id=None emoji=<PartialEmoji animated=False name='👍' id=None> event_type='REACTION_ADD' member=None>

追加するコード（＋デバッグ付き）

• payloadの変数名は各クラスで使用する変数に置き換える

  
      event_channel = self.bot.get_channel(payload.channel_id)
      reaction_member = await self.bot.fetch_user(payload.user_id)
      if isinstance(event_channel, discord.DMChannel):
          print(f"[DEBUG] {self.__class__.__name__} : (reaction: {reaction_member.name}/{payload.emoji.name}) BOT間のDMメッセージのためreturnします")  # noqa : E501
          return

[supleiades]

• 作業対象のファイル

  view_TimesChannel
  times
  rolesmanager

[supleiades]

payload.memberにせず

member = await self.bot.fetch_user(payload.user_id)
member.bot

にするでよいかも。DMのチャンネルかどうかの判定よりここではbotかどうかだけの判定にしぼろう
