Pushpad is not able to send notifcation from node.js app - web-push

Question

I have written the code shown below to send the push notification:
const pushpad = require('pushpad');
require('dotenv').config();
const axios = require('axios');
const project = new pushpad.Pushpad({
authToken: process.env.PUSH_PAD_AUTH_TOKEN,
projectId: process.env.PUSH_PAD_PROJECT_ID
});
console.log('called pushpad');
let notification = new pushpad.Notification({
project: project,
body: 'Hello world!',
title: 'Website Name',
targetUrl: 'http://example.com',
iconUrl: 'http://example.com/assets/icon.png',
imageUrl: 'http://example.com/assets/image.png',
ttl: 604800,
requireInteraction: true,
customData: '123',
actions: [
{
title: 'My Button 1',
targetUrl: 'http://example.com/button-link',
icon: 'http://example.com/assets/button-icon.png',
action: 'myActionName'
}
],
starred: true,
sendAt: new Date(Date.UTC(2016, 7 - 1, 25, 10, 9)),
customMetrics: ['examples', 'another_metric']
});
// deliver to everyone
notification.broadcast(function (err, result) {
console.log("error is " + err);
});
module.exports = notification;
but somehow, as soon as I run this code, it gives me error Unprocessable Entity . So how to solve this error ?

Answer 1

Probably you have entered some wrong parameters. For example customMetrics must be defined in your project settings before using them.
Try the same code with a simple notification:
let notification = new pushpad.Notification({
project: project,
body: 'Hello world!'
});
