我正在使用MERN Stack和Redux以及Redux Toolkit制作一个社交媒体应用程序。
我做了addRemoveFriend函数，检查用户是否已经是朋友，然后删除它，否则它会添加它，但它不工作，并给予我这个错误：

"User validation failed: password: Path `password` is required."

addRemoveFriend：

export const addRemoveFriend = async (req, res) => {
  try {
    const { id, friendId } = req.params;
    const user = await User.findById(id);
    const friend = await User.findById(friendId);

    if (user.friends.includes(friendId)) {
      user.friends = user.friends.filter((id) => id !== friendId);
      friend.friends = friend.friends.filter((id) => id !== id);
    } else {
      user.friends.push(friendId);
      friend.friends.push(id);
    }
    await user.save();
    await friend.save();

    const friends = await Promise.all(
      user.friends.map((id) => User.findById(id))
    );
    const formattedFriends = friends.map(
      ({ _id, firstName, lastName, username, avatarPath }) => {
        return { _id, firstName, lastName, username, avatarPath };
      }
    );

    res.status(200).json(formattedFriends);
  } catch (err) {
    res.status(404).json({ error: err.message });
  }
};

用户模型：

const UserSchema = new mongoose.Schema(
  {
    ...,
    password: {
      type: String,
      required: true,
      min: 8,
      max: 50,
    },
    friends: {
      type: Array,
      default: [],
    },
  },
  { timestamps: true }
);
