Has anyone who has integrated WhatsApp using the Evolution API run into the problem where the QR code doesn’t appear when you click “Get QR Code”? If you figured out the fix, what was the root cause?
I need to understand why the manager isn’t showing the pairing code.

This QR code problem happens because the version number in your config file is old. Here’s the drill:
Find the real version: Go to WhatsApp Web, open the Settings, and the current version is hiding at the very bottom of that left menu pane.
Paste that number into your .env file. Make sure you change both of these lines to the new number (don’t forget to update your phone app, too!):
CONFIG_SESSION_PHONE_VERSION=…
WEB_VERSION=…
It should work perfectly after that!
