Hi, I am building a small Node.js service that connects to WhatsApp Web using the Baileys library and generates a QR code so users can link their WhatsApp account. The project is deployed on Railway and runs an Express server. My goal is simple: Create a WhatsApp session per store. Generate a QR code for linking WhatsApp. Send messages later using the session. The server starts correctly and the endpoint /session/create works.However, the QR code is never generated, and the endpoint /session/qr/:store_id always returns: QR nu este gata. Refresh in cateva secunde. So it seems the connection.update event is not returning the qr value, or the session is not properly initialized. What I need help with: Fix the QR generation so it appears reliably Make sure the session connects correctly with Baileys Ensure the Express endpoint /session/qr/:store_id returns the QR image Ideally add stable reconnection logic Tech stack: Node.js Express Baileys (@whiskeysockets/baileys) QRCode package Hosted on Railway I will provide my current index.js file. The code is already mostly implemented but something in the session/QR flow is not working. If possible, I would also like: stable multi-session support (one WhatsApp per store) clean working code Thanks!
