ReflectionException Issue on Magento 2.1.x

I actually wanted to upgrade your extension to 1.2.1 but got an error message, so I went back to my original version.

and the error i get at setup:upgrade after upgrading your module to 1.2.1 is:

  Class Magento\Framework\Serialize\Serializer\Serialize does not exist


The issue is due to an incompatibility issue on Magento 2.1.x.
