Node created but can not be returned

[ljhhuxiaoba]

I execute a query 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:
OPTIONAL MATCH () WITH * WHERE FALSE CREATE (a{k:1}) RETURN a as n

Result:

1. 1. "n"
2. (empty list or set)
3. 1. "Nodes created: 1"
   2. "Properties set: 1"
   3. "Cached execution: 0"
   4. "Query internal execution time: 1.450015 milliseconds"

You can see that node a has been created, but it has not been returned！
On the other hand I suspect that the node shouldn't have been created because "WITH * WHERE FALSE" filters out previous matches to all records.And this query really doesn't create a node on My Neo4j Database.
