LAC sysfilter has become case sensitive after upgrading from 4.0 to 5.x
Release : 5.x
Component : LIVE API CREATOR
"sysfilter=equal(language:'en-US'), the query returns 200 OK ... but when we search with "sysfilter=equal(Language:'en-US'), the query returns response 500 error.
This is the correct the behavior which was changed after the 4.0 release and now Sysfilter is Case - Sensitive.
