GET response data from request promise giving error - node.js

Question

Using request promise module to do a post API call. The code is to get 'city' detail from the google maps api JSON output as below:
var rp = require('request-promise');
............
app.get('/check_promise', function(req,res) {
var option1 = {
url: 'https://maps.googleapis.com/maps/api/geocode/json?address=Florence',
method: 'POST',
headers: {
'Content-Type': 'application/json'
},
json: true
}
rp(option1)
.then(function(response) {
console.log(response.data.results[0].formatted_address);
})
.catch(function(error){
console.log(error);
});
});
But the
console.log(response.data.results[0].formatted_address);
gives the below error:
TypeError: Cannot read property 'results' of undefined
