Pairing code is not working

[gabrielhhaber]

Welcome!

• Yes, I have searched for similar issues on GitHub and found none.

What did you do?

I'm trying to connect the Evolution API with a pairing code. The QR code works fine but the pairing code is not working. WhatsApp on my phone says the code is invalid. I also tried using the Evolution Manager v2 to generate the code instead of a Python script but it doesn't work too.

What did you expect?

The provided pairing code for authentication should work properly.

What did you observe instead of what you expected?

The pairing code is generated but when I enter it on WhatsApp's phone app it says that the code is invalid.

evolution version: 2.2.3 CONFIG_SESSION_PHONE_VERSION=2.3000.1025110696

I've just tested it with CONFIG_SESSION_PHONE_VERSION=2.3000.1023204200 and works like a charm

Is this variable still used? I thought it was discontinued or removed from the API.
