Hibernate QueryException Named parameter not bound error

I keep getting the error org.hibernate.QueryException: Named parameter not bound : item when I start my transaction in JPA using EntityManager createNativeQuery. I have my code below utilizing the entity manager, along with my embeddedID class (for the composite key) and my persistence entity bean. Is there a problem in my query syntax? I am not sure as I've tried multiple ways of formatting the sql (coming from a properties file where there resides multiple sqls used throughout the project, and attempting to persist data to an oracle db). I am not sure why I keep falling on this error. I want to persist this data to my oracle database but this error keeps preventing that.

Query from query.properties file:

insertPromoData =INSERT INTO TEST.U_USER_PROMO (ITEM, LOC, WK_START, NUMBER_OF_WEEKS, TYPE, FCSTID, QTY, U_TIMESTAMP) VALUES (:item, :location, :wkStart, :numberOfWeeks, :type, :fcstId, :quantity, SYSDATE)
