问Neo4jClient“案例时”与返回一起

EN

RETURN CASE WHEN groups IS NOT NULL THEN collect(groups) ELSE NULL END

.Return((groups) => new
{
    Board = parentBoard.As<Board>(),
    Groups = Return.As<Groups>("CASE WHEN groups IS NOT NULL THEN collect(groups) ELSE NULL END")
});

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

First, try and review the exception below to work out what broke.
