[BUG] stream:error code='515' Causing Connection Termination During Pairing

[felipeduarte26]

Description:

I'm encountering an issue where the WhatsApp connection consistently terminates with a stream:error code='515' after successfully pairing. This prevents my application from maintaining a stable connection with WhatsApp.

Steps to Reproduce:

Setup:

Integrated Baileys into a Fastify-based API.
Configured authentication using useMultiFileAuthState.
Attempted to pair by scanning the QR code displayed in the terminal.
Execution:

Ran the server.
Scanned the QR code with the WhatsApp application on my mobile device.
Observed the connection process in the logs.

Outcome:

I changed the logic, according to some tutorials, and it worked, thanks
