IBM Worklight - Adapter procedure response returns "zero results" from Google Places - ibm-mobilefirst

Question

I am getting status "ZERO RESULTS" when I invoke HTTP Adapter using Indian latitude and longitude to search for any service like food, malls etc.
Here is my adapter implementation:
function getGooglePlaces(location,name) {
var input = {
method : 'get',
returnedContentType : 'json',
path : 'maps/api/place/search/json',
headers: {
Host: 'maps.googleapis.com'
},
parameters : {
'key' : My Key,
'location' : location,
'radius' : '10000',
'sensor' : 'false',
'name' : name
}
};
var response = WL.Server.invokeHttp(input);
return response;
}
}
The JSON response for indian coordinates.
results is the array of places searched

Answer 1

I have used the following and got a valid response, using a Worklight adapter.
Note that I passed name and location as part of the parameters object and not like you did (just for the sake of simplification)
I added a type parameter for "restaurant"
I increased the radius
With the above, I got results.
Looks to me like this is a matter of tweaking the request parameters. Nothing related to Worklight adapters here, as it works.
