OptionChain giving empty response

I am getting empty data in success response. i want to know the reason of it. is it because of not active F&O segment in my account?

may be date and expiry placed wrong

Glad to hear the problem’s fixed for you, @Davinci_Code and @sagar_gajera . If any similar issues arise in the future, sending a curl request would aid in troubleshooting and processing.
