Description:
I am trying to connect to the github api through a siddhi app using the bellow code,

@app:name("SiddhiAppGitHub2")
@app:description("Description of the plan")

@sink(type='http-request' , publisher.url='https://api.github.com/repos/wso2/product-sp/releases', method='GET', sink.id='releases_data', @Map(type='json'))
define stream GitReleaseInputStream(state string);

@source(type='http-response' , sink.id='release_data', http.status.code='200', @Map(type='json', @attributes(state='$.assets.[0].state')))
define stream GitReleaseCatchInputStream(state string);

@sink(type='log')
define stream GitReleaseOutputStream(state string);

from GitReleaseCatchInputStream
select state
insert into GitReleaseOutputStream;

But I am not getting a response. Bellow is the response I received when I requested through "Postman"
