不应该报错500

reproduction:
{code}
create function count_sec as 
"com.timecho.udf.normal.TestSessionTimeWindowAccessStrategy";

CREATE DATABASE root.udf;
CREATE TIMESERIES root.udf.d1.s1 WITH DATATYPE=text, ENCODING=PLAIN;
CREATE TIMESERIES root.udf.d1.s2 WITH DATATYPE=text, ENCODING=PLAIN;

insert into root.udf.d1 (time, s1, s2) values (1, 'udf', 'trigger'),(2, 'some' 
, 'old'),(3, null, 'trigger'),(9, 'udf', 'new'),(5, 'woman', 'udf'),(12, 
'trigger', null),(14, 'udf', 14),(18, 'udf', 16),(21, 'trigger', 18),(24, 
'udf', 20);

select count_sec(s1, 'max_interval'=1, 'standard'=null) from root.udf.d1;
select count_sec(s1, 'max_interval'=1, 'standard'=NULL) from root.udf.d1;
{code}
