GeoJSON parse node - node.js

Question

I am getting an 500 error 'unexpected problem has occurred' when I parse the GeoJSON data from this weather API site using node app.
The code is a simple proxy server to receive request from client for weather info on a particular site and process an async request to the weatherAPI, when the response is received its send to the client. When I replace the URL with something that returns JSON it works. The issue is when the response data is GeoJSON.
Appreciate if anyone help shed some light on how to parse the GeoJSON response in node JavaScript.
Thank you in advance.
Here is my node app code:
function initialize() {
// Setting URL and headers for request
var options = {
url: 'https://api.weather.xxx/points/39.7456,-97.0892',
headers: {
'User-Agent': 'request'
}
};
// Return new promise
return new Promise(function(resolve, reject) {
// Do async job
request.get(options, function(err, resp, body) {
if (err) {
reject(err);
} else {
resolve(JSON.parse(body));
}
})
})
}
http.createServer(function (req, res) {
var initializePromise = initialize();
initializePromise.then(function(result) {
var geoDetails = result;
console.log("Initialized Geo details");
// Use user details from here
console.log(geoDetails);
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.write('request successfully proxied!' + '\n' +
JSON.stringify(geoDetails, true, 2));
res.end();
}, function(err) {
console.log(err);
})
}).listen(9000);
Here is the GeoJSON data :
{
"#context": [
"...",
{
"wx": "...",
"s": "...",
"geo": "...",
"unit": "...",
"#vocab": "...",

"unitCode": "unit:m"
},
"bearing": {

}
}
},
...
}
}
I am interested in getting all the Properties in plain text or JSON.

Modify your headers to accept JSON.
var options = {
url: 'https://api.weather.gov/points/39.7456,-97.0892',
headers: {
'user-agent': 'request',
'accept': 'application/json'
}
};
