First example doesnt work

[horr0rjkeezor]

Code:
`const path = require('path');
const MTProto = require('@mtproto/core');

const api_id = "1663794";
const api_hash = "d011ea569072f733217411d392cce73";

// 1. Create instance
const mtproto = new MTProto({
api_id,
api_hash,

storageOptions: {
    path: path.resolve(__dirname, './data/1.json'),
},

});
console.log("test before");
// 2. Print the user country code
mtproto.call('help.getNearestDc').then(result => {
console.log('country:', result.country);
});
console.log("test after");`

When i run, i get this messages in console:

D:\xampp\htdocs\telegrr>node index.js
test before
test after

And what i can do with this? Method "help.getNearestDc", does not respond. I wait five minutes.
