Resolution

I n the past it was mandatory to have the same version of Policymanager as you got a error the version did not match  , currently in most cases using a newer PM with a older Gateway version works oke  .

Unfortunlay in this case there is a compatibility issue with evaluate json assertions which needs a java class which is depreciated , the workaround is to use a older version of policy manager and upgrade the gateway to CR5 .
