"Error null" when Automatically Retriev Fields from "Report Query" wizard

[sagarnikam123]

I have few parameters,as (Parameter class, Prompt ?, Default value Expression)

1)PEMID_input--> string, prompt yes, no

2)month_year--> .String,prompt yes, no

3)transparency_input--> String,prompt yes, no

4)month--> String, NO, $P{month_year}.split("-" )[0]

5)year-->String ,NO, $P{month_year}.split("-")[1]

6)StartDate-->String,No, $P{month_year}.split("-")[0]=="April" ? $P{month_year}.split("-")[1].concat("-04-01") :   $P{month_year}.split("-")[1].concat("-10-01")

7) EndDate-->String, No, $P{month_year}.split("-")[0]=="April" ? $P{month_year}.split("-")[1].concat("-09-30") : $P{month_year}.split("-")[1].concat("-03-31")

8)month_selector-->String, No, ($P{month_year}.split("-")[0]=="April") ? ($P{month_year}.split("-")[0].concat(",May,June,July,August,September")) : ($P{month_year}.split("-")[0].concat(",November,December,January,February,March"))

all parameters giving values in report when running with no queries(I tested them).

when I am running query by replacing  parametera to values, it also works fine

but when running with paramete gives,    Error:null. while retrieving fields in Report Query wizard 

even though I run report,& give specified parameters it give below error
