.net 在dotnet for apache spark中执行VectorUdf时出错

我正在使用.net for ApacheSpark，我有以下代码

   var spark = SparkSession.Builder().AppName("sample").GetOrCreate();
   Func<Column, Column> cubed_udf = VectorUdf<Int64DataFrameColumn, Int64DataFrameColumn>((a) => { return a ; });
   var df = spark.Range(1, 10);
   df.Select(cubed_udf(df["id"])).Show();

我得到下面的错误。有人能帮我吗
