在创建新的Device文档之前，您可以直接在后端逻辑中添加验证，以检查您要发送的设备是否存在于数据库中。
您可以使用$in运算符：

const createDevice = async (req, res) => {
  try {
    const { deviceName, category, incompatibleWithDevices} = req.body;
    const incompatibleDevices = await Devices.find({ deviceName: { $in incompatibleWithDevices }});
    // Here, you do the validation if some deviceName are maybe invalid.
    // At least one device will be invalid if returned array is not the same
    // size as the input array.
    if (incompatibleDevices.length !== incompatibleWithDevices.length) {
      return res.status(400).json({ sucess: false });
    }
    // Here you can add the logic that creates the new device since
    // all inputs are valid.
  } catch (error) {
    return res.status(400).json({ success: false })
  }
}
