NPE in ESQL LIMIT with parameter #130908
Description
Since #128464
A query like ROW a=1 | LIMIT null ends up with:
java.lang.NullPointerException: Cannot invoke "Object.getClass()" because "val" is null at org.elasticsearch.xpack.esql.parser.LogicalPlanBuilder.visitLimitCommand(LogicalPlanBuilder.java:407) Same with:
{ "query": "ROW a=1 | LIMIT ?", "params": [ null ] }
