Cloud function error. Error or error in my code: www.googleapis.com network timeout. Please try again

Question

I created a function to send notifications via firebase, and I get this error:

Error fetching user data (a0ZdYX3IgCbssNNRP2oPZyAAEOt1): { Error: www.googleapis.com network timeout. Please try again.
    at FirebaseAppError.Error (native)

  errorInfo: 
   { code: 'app/network-timeout',
     message: 'www.googleapis.com network timeout. Please try again.' } }

Is it because of me (firebase restriction for free?) Or a bug on google server and I just need to wait?

My function (I know that a function can be improved in speed, but the question does not exist, I just want to know if I am the cause of this error). This function sends a notification to users who installed the application x a day ago, retrieving the day of creating your account and their fcm token is stored in the database:

'use strict';

const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);

exports.sendNotificationToNewUser = functions.https.onRequest((request, response) => {

    Date.prototype.sameDay = function(d) {
        return this.getFullYear() === d.getFullYear()
        && this.getDate() === d.getDate()
        && this.getMonth() === d.getMonth();
    }

    var query = admin.database().ref("users").orderByKey();
    var defaultAuth = admin.auth();
    query.once("value")
    .then(function(snapshot) {
        snapshot.forEach(function(childSnapshot) {
            var user_id = childSnapshot.key;
            var user_data = childSnapshot.val();

            admin.auth().getUser(user_id)
            .then(function(userRecord) {
                var create_date = userRecord.metadata.createdAt
                var date_now = new Date(Date.now());
                console.log("Creation date:", create_date);
                create_date.setDate(create_date.getDate()+4);
                if (create_date.sameDay(date_now)) {

                    var registrationToken = user_data.fcm_token;

                    const payload = {
                        notification: {
                            body: "blabla",
                            sound: "default"
                        },
                        "data" : {
                            "key" : "XXX",
                            "value" : "playstore"
                        }
                    };

                    var options = {
                        priority: "high",
                        collapseKey: "playstore"
                    };

                    // Send a message to the device corresponding to the provided
                    // registration token with the provided options.
                    admin.messaging().sendToDevice(registrationToken, payload, options)
                    .then(function(response) {
                        console.log("Successfully sent message:", response);
                    })
                    .catch(function(error) {
                        console.log("Error sending message:", error);
                    });
                }
            })
            .catch(function(error) {
                console.log("Error fetching user data ("+user_id+"):", error);
            });
    });
});
response.send("OK");
})
