queryable:sourcev4 gives error without generate code

[fiorenzino]

in absence of @q on field, we should have:

@OverRide
public Predicate[] query(CriteriaBuilder criteriaBuilder, Root<${className}> root) throws Exception {
    var predicates = new ArrayList<Predicate>();
    return predicates.toArray(new Predicate[]{});
}

we have this error:

[ERROR] 
java.lang.NullPointerException: Cannot invoke "org.jboss.forge.roaster.model.source.MethodSource.setBody(String)" because "templateMethod" is null
   at it.ness.queryable.builder.QueryableV4Builder.createRsService (QueryableV4Builder.java:103)
