After patching SUPEE-10415, causes an error “Unsupported data type N” Solution: The cause of this issue is not having SUPEE-8788 V2 installed. To fix this, download Magento 1.9.3.7 and copy

lib/Unserialize/Parser.php
lib/Unserialize/Reader/Arr.php
lib/Unserialize/Reader/ArrValue.php
lib/Unserialize/Reader/Null.php

files to your website. check if any changes between files.

Please take Security Patch SUPEE-10415 - Possible Issues? as reference.
