Neo4jClient:与OnCreate合并会导致中断的Cypher查询

cypher examples this 在这里,我们认为这应该是非常直接的:

public class KlientNode
{
    [JsonProperty(PropertyName = "id")]
    public Guid Id { get; set; }
}

var neuerKlient = new KlientNode { Id = ev.KlientId };
var kq = graphClient.Cypher
    .Merge("(klient:Klient { id: {klientId} })")
    .OnCreate()
    .Set("klient = {neuerKlient}").WithParams(new
    {
        klientId = neuerKlient.Id,
        neuerKlient
    });
Console.WriteLine(kq.Query.DebugQueryText);
kq.ExecuteWithoutResults();

不幸的是,这会导致以下输出和异常:

MERGE (klient:Klient { id: "80248429-ea80-4a5d-8d4e-88dc1499ea8a" })
ON CREATE
SET klient = {
  "id": "80248429-ea80-4a5d-8d4e-88dc1499ea8a"
}
Neo4jClient.NeoException: SyntaxError: Invalid input 'N': expected 'p/P' (line 5, column 2 (offset: 250))
"ON CREATE"
      ^

原因似乎是 "id" SET klient = ...

当我们几乎一字不差地复制示例时,谁知道是什么导致了中断的查询?
