In the context of data services an unknown internal server error occured

[rahul_dubey5]

Hi,

I am trying fetch the data based on the date range given by the user,

the url looks like this :

http://<>/<project_name>/<entity_set>?$filter=date_field ge '2018-01-01T00:00:00' and date_field ge '2018-01-01T00:00:00'

and when i execute my service, the import parameter "it_filter_select_options" is getting filled and using those dates i am fetching all the required data.

The export parameter ET_ENTITY_SET is getting filled after complete execution i am getting this error :

"In the context of data services an unknown internal server error occured"

there are no error logs found for this error.

can anyone please help me.

Can u check if ur returned data is having any empty dates? If yes then change the entity property for that date nullable true
