Get Dataset Parameters from REST API

I tried get the list of parameters using REST API as: https://api.powerbi.com/v1.0/myorg/groups/$group_id/datasets/$dataset_id/parameters" , but get the response as  empty array even though parameters are managed.

Result bject(stdClass)#2 (2) { ["@odata.context"]=> string(98) "https://api.powerbi.com/v1.0/myorg/groups/$group_id/$metadata#parameters" ["value"]=> array(0) { } }

Does anybody get success in this parameters REST Api, please share your idea?  Thanks in Advance.
