Inconsistent results caused by adding “ORDER BY"

[ljhhuxiaoba]

I execute two queries on my empty RedisGraph and get an error.

Redis version:7.2.0
RedisGraph version: v2.12.10
operating system: windows 11
API：Cypher version 9

Steps to reproduce:

Execute the following two queries separately
GRAPH.QUERY graph "UNWIND NULL AS a0 OPTIONAL MATCH (:LL) RETURN percentileDisc(NULL,0) AS a1"
GRAPH.QUERY graph "UNWIND NULL AS a0 OPTIONAL MATCH (:LL) RETURN percentileDisc(NULL,0) AS a1 ORDER BY TRUE"

I think these two queries are equivalent, but the first query returns a single row of results, while the second returns an empty result.
I think the "ORDER BY TRUE" clause should not change the return result.
