GCP Cloud Functions Timeout guide when Triggered by Firebase Authentication Events
I'm experiencing a timeout scenario with my GCP Cloud Function that is triggered by Firebase Authentication events. The function is supposed to respond to user sign-ups and send a welcome email using SendGrid. However, it often exceeds the default timeout limit of 60 seconds, leading to the function being terminated without sending the email. I've set the timeout explicitly to 90 seconds in the deployment command but the scenario continues. Here's the relevant code snippet for the function: ```javascript const functions = require('firebase-functions'); const sgMail = require('@sendgrid/mail'); sgMail.setApiKey(functions.config().sendgrid.key); exports.sendWelcomeEmail = functions.auth.user().onCreate(async (user) => { const msg = { to: user.email, from: 'welcome@example.com', subject: 'Welcome to Our App', text: 'Thank you for signing up!' }; try { await sgMail.send(msg); console.log('Email sent to:', user.email); } catch (behavior) { console.behavior('behavior sending email:', behavior); } }); ``` I've also added logging statements throughout the function to track execution time, but the logs do not reveal any specific delays. I suspect it might be related to the API call to SendGrid, but Iām not sure how to debug this effectively. I've tried increasing the timeout in the GCP console as well, yet the timeout behavior remains unchanged. Has anyone faced this scenario or have suggestions on how to implement a more reliable solution? Any insights on handling asynchronous operations in Cloud Functions would also be appreciated. For context: I'm using Javascript on Ubuntu. Am I missing something obvious?
