Cloud Function Deployment Error on Flutter Web

[Murphy]

Cloud function deployment failed

I’m working on a Flutter web app that needs to send SMS and emails through Twilio and SendGrid. To handle emails, I created a Google Cloud Function that triggers every time a new document is created in a Firestore collection called apiusers. The function is supposed to send an email using SendGrid whenever a new user is added to this collection.

Could not create or update Cloud Run service sendusernotification, Container Healthcheck failed. Revision 'sendusernotification-00001-wof' is not ready and cannot serve traffic. The user-provided container failed to start and listen on the port defined provided by the PORT=8080 environment variable within the allocated timeout. This can happen when the container port is misconfigured or if the timeout is too short. The healtcheck timeout can be extended. Logs for this revision might contain more information.`

There must be some compile time or runtime error that prevents the function to start.

You can check the functions logs in GCP, maybe it throws some obvious error.

You may want to check if 'npm run build ’ works. Without the source code and error in the code it’s impossible to say what’s wrong.

The following is my index.js file

const { onDocumentCreated } = require('firebase-functions/v2/firestore');
const functions = require('firebase-functions');
const admin = require('firebase-admin');
const sgMail = require('@sendgrid/mail');
const twilio = require('twilio');

admin.initializeApp();

const SENDGRID_API_KEY =functions.config().sendgrid.key;
const TWILIO_SID = functions.config().twilio.sid;
const TWILIO_TOKEN = functions.config().twilio.token;

sgMail.setApiKey(SENDGRID_API_KEY);


const twilioClient = twilio(TWILIO_SID, TWILIO_TOKEN);

exports.sendUserNotification = onDocumentCreated(
    {
        document: '<Firestore-Collection>/{userId}',
        region: 'europe-west2',
    },
    async (event) => {
        const snapshot = event.data;
        const userData = snapshot.data();

      
        const { Email, FirstName, LastName, Password } = userData;

     
        const emailMessage = {
            to: <receiver-email-address>,
            from: <sender-email-address>
            subject: 'New User Account Created',
            text: `An Email ${Email} has been created with account name ${FirstName} ${LastName}. Here are the login credentials: username - ${Email}, password - ${Password}`,
        };

        const smsMsg = {
            body: `Account created for ${FirstName} ${LastName}. Username: ${Email}, password: ${Password}`,
            from: <sender-contact number>
            to: <receiver-contact-number>,
        };

        try {
            await sgMail.send(emailMessage);
            console.log('Email sent successfully');
            await twilioClient.messages.create(smsMsg);
            console.log('SMS sent successfully');
        } catch (error) {
            console.error('Error sending notification:', error);
        }
    }
);

This is my package.json

You are missing values for:

• document in the function definition - I replaced it with name-of-the-collection
• to and from in the emailMessage
• as well as from and to in smsMsg

exports.sendUserNotification = onDocumentCreated(
    {
        document: 'name-of-the-collection/{userId}',
        region: 'europe-west2',
    },
    async (event) => {
        const snapshot = event.data;
        const userData = snapshot.data();


        const { Email, FirstName, LastName, Password } = userData;


        const emailMessage = {
            to: Email,
            from: "my-email-address",
            subject: 'New User Account Created',
            text: `An Email ${Email} has been created with account name ${FirstName} ${LastName}. Here are the login credentials: username - ${Email}, password - ${Password}`,
        };

        const smsMsg = {
            body: `Account created for ${FirstName} ${LastName}. Username: ${Email}, password: ${Password}`,
            from: "my-contact-number",
            to: Email,
        };

        try {
            await sgMail.send(emailMessage);
            console.log('Email sent successfully');
            await twilioClient.messages.create(smsMsg);
            console.log('SMS sent successfully');
        } catch (error) {
            console.error('Error sending notification:', error);
        }
    }
);

Btw I recommend using TypeScript for writing functions, if you use VS Code it will detect these type problems immediately.
