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
]
}
