Hi JayNEC,
policy-based VPN was initially removed from the 15.1X49 software train but was reintroduced in 15.1X49-D50. VPN client support was also initially removed and the reintroduced in 15.1X49-D60.
If you look in the attached configuration you will also see the "unsupported platform" multiple times. In this case it's due to missing support for policy-based VPN.
So first step would be to upgrade to at least 15.1X49-D60 and preferably 15.1X49-D70. Then try again.
