ValidationError:令牌验证失败:user:路径`user`是必需的

我正在尝试在列中创建一个用户 sellerKeys 在另一列中。我得到了:

ValidationError:令牌验证失败:user:路径“user”是必需的。

const createUser = async (userBody) => {
  if (await User.isEmailTaken(userBody.email)) {
    throw new ApiError(httpStatus.BAD_REQUEST, 'Email already taken');
  }
  // return User.create(userBody);
  const createdUser = await User.create(userBody);
  const sellerId = createdUser._id;
  const user = createdUser.name;
  console.log(user);

  const sellerkeyBody = {
    sellerId: sellerId, // Replace with the actual sellerId for the user
    user: user, 
    shopify: {
      isActive: false,
    erp: {
      isActive: false, 
    },
    magento: {
      isActive: false,
    },
    lazada: {
      isActive: false, 
    },
    shopee: {
      isActive: false, 
    }
    }
  };
  
  const createdSellerKey = await createSellerkey(sellerkeyBody);
 await createdUser.save();
 return { user: createdUser, sellerKey: createdSellerKey };
};

这是我的代码
