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

Query:
OPTIONAL MATCH (n0:L2)<-[r0:T0]-(n1)-[r1:T3]-(n3) WITH r0 WHERE (r1.k) RETURN *

Error message:
"Unable to resolve filtered alias 'r1'"

I wonder if redisgraph does not allow relationships to be referenced in predicates, whereas nodes can be referenced.
