Getting Null response from api

SwatiDesale

I'm trying to get access_token using 'https://api.kite.trade/session/token' by passing request_token but get null response sometimes. the issue is not frequent, it is working fine sometimes but get issue without any error message which is very difficult to find the root cause

Can you run in debug mode and paste the complete stack trace here?
Make sure to remove app and client specific tokens.

const get_access_token = async (request_token,check_sum,api_key) => {
let url = 'https://api.kite.trade/session/token';
var post_data = querystring.stringify({
api_key : api_key,
'request_token': request_token,
'checksum': check_sum
});
return new Promise(function (resolve, reject) {
request.post({
headers: {'content-type' : 'application/x-www-form-urlencoded'},
url: url,
body: post_data
}, function(error, response, body){
if (!error && response.statusCode == 200) {
resolve(body);
} else {
console.log(error);
reject(error);
}
});
});
}

this is the function where I'm trying to get the access token and when try to console the error get the null value

You can use the official client library.

Can you add the catch block and try printing the error message?
Make sure, you are passing request_token,check_sum,api_key values properly.
