경우 ArgumentException이 결과는 다음 쿼리와

Question

비어있을 때 결과가 비어있을 때 나는 Neo4jclient 내부 ArgumentException이 얻을 :

이

graphClient.Cypher 
      .Match("(a:Application {Id: {pId}})") 
      .WithParams(new { pId = request.Id }) 
      .With("a") 
      .OptionalMatch("(a)-[:Uses]->(db:Database)") 
      .ReturnDistinct(db => db.As<DatabaseDto>()); 

결과는 다음과 같습니다

Additional information: Neo4j returned a valid response, however Neo4jClient was unable to deserialize into the object structure you supplied. 

Include this raw JSON, with any sensitive values replaced with non-sensitive equivalents: 


{ 
    "columns" : [ "db" ], 
    "data" : [ [ null ] ] 
}
