Hey can i create a function which uses whatsapp web js (which under the hood opens chromium browser via pupeteer) because getting this err:-
Error: Failed to launch the browser process! spawn /usr/local/server/src/function/node_modules/puppeteer/.local-chromium/linux-982053/chrome-linux/chrome ENOENT
TROUBLESHOOTING: https://github.com/puppeteer/puppeteer/blob/main/docs/troubleshooting.md
CODE:-
Plain text
const qrcode = require("qrcode-terminal");
module.exports = async (context) => { const whatsappclient = new Client({ authStrategy: new LocalAuth() // puppeteer: { args: ['--no-sandbox', '--disable-setuid-sandbox'] } });
whatsappclient.initialize();
whatsappclient.on("qr", (qr) => { qrcode.generate(qr, { small: true }); context.log(qr); });
whatsappclient.on("message", async (msg) => { context.log("MESSAGE:- " + msg.body); });
if (req.method === 'GET') { if (req.path === '/message') { const phoneNumber = req.query.phoneNumber; const message = req.query.message; const chatId = phoneNumber + "@c.us";
try { // Wait for client to be ready before sending message await new Promise((resolve) => whatsappclient.on("ready", resolve));
const response = await whatsappclient.sendMessage(chatId, message); context.log("Message sent to:", phoneNumber, chatId); context.log(response); return res.send("Message sent successfully."); } catch (err) { context.error("Error sending message:", err); return res.send("Error sending message."); }
} } // Consider returning a placeholder response to indicate processing // (optional, depending on your needs) // return new Promise((resolve) => setTimeout(resolve, 1000));};Summary
Developers are trying to create a function using WhatsApp Web JS, which opens a Chromium browser via Puppeteer, but they are encountering an error related to launching the browser process.
The solution involves setting up the build command to install Chromium in the functions container and updating WhatsAppClient/Puppeteer to reference the new location of Chromium.
Code snippet provided for reference:
- Initialize WhatsApp client with specific authentication strategy
- Use QR code to set up client
- Handle incoming messages and send messages
- Implement error handling for message sending
Ensure correct environment variables, build settings, and dependencies are in place for successful implementation.
