unexpected end of JSON input in req.EndStruct(body)

[MalarvizhiK]

The below code gives unexpected end of JSON input. The URL will retrieve 2000 documents from Cloudant database.

req := request.New().Get(client.Path + path)
req.SetBasicAuth(client.Username, client.Password)
req.Header.Add("Accept-Encoding", "application/json")
req.Debug = true

body := &cloudantLib.Resp{}
resp, _, errs := req.EndStruct(body)

Is there any limit in the response body ? When we try with small document size like 100, we don't get any error and it works fine.
