Cannot pass parameters in `algo.dfs.stream` call

[maxlazarus]

Tried to follow instructions for passing parameters on https://neo4j.com/docs/graph-algorithms/3.5/projected-graph-model/cypher-projection/#cypher-projection-parameters

Using Neo4j 3.5.3, graph-algorithms 3.5.4.0

Example: Query 1: setup nodes and relationships

create (:TestNode{key:1, name:"A"})-[:CONNECTS]->(:TestNode{key:2, name:"B"})

Query 2: setup param

:param name => 'B'

Query 3 succeeds, the $name param is present but not used in the projection:

MATCH (start:TestNode{key:1})
CALL algo.dfs.stream(
    'match (t:TestNode) return id(t) as id',
    'match (t:TestNode)-[c:CONNECTS]->(u:TestNode) return id(t) as source, id(u) as target',
    '>',
    id(start),
    {
        graph:'cypher',
        params: {name: $name}
    }
)
YIELD nodeIds
UNWIND nodeIds AS nodeId
WITH algo.asNode(nodeId) AS n
RETURN n

Query 4 fails:

MATCH (start:TestNode{key:1})
CALL algo.dfs.stream(
    'match (t:TestNode) where t.name <> $name return id(t) as id',
    'match (t:TestNode)-[c:CONNECTS]->(u:TestNode) return id(t) as source, id(u) as target',
    '>',
    id(start),
    {
        graph:'cypher',
        params: {name: $name}
    }
)
YIELD nodeIds
UNWIND nodeIds AS nodeId
WITH algo.asNode(nodeId) AS n
RETURN n

Error: Neo.ClientError.Procedure.ProcedureCallFailed: Failed to invoke procedure algo.dfs.stream: Caused by: org.neo4j.cypher.ParameterNotFoundException: Expected parameter(s): name

Please see the preview release of the Graph Data Science library (https://github.com/neo4j/graph-data-science), or download the jar from our download center -- the preview documents are here.

We're transitioning to the GDS, so hopefully the updated graph loaders will address your issues. If you continue to run into problems, please open an issue on the new repo.
