[Bug] VIA can't fetch V3 definitions for Keyboard K8 Pro V3 pre-compiled firmware; received invalid protocol version from device

Describe the Bug

I downloaded the precompiled firmware for the RGB Ansi version of the K8 Pro that's in the repo and flashed it but whenever I open VIA now, I get these errors when loading up the keyboard in the program (on the webapp and on desktop)

Is AutoHotKey / Karabiner installed

• [ ] AutoHotKey (Windows)
• [ ] Karabiner (macOS)

Other keyboard-related software installed

VIA

Additional Context

I also tried to manually compile the firmware but then VIA wouldn't pick up on the keyboard at all because it didn't provide the via json needed for the keyboard when I manually built it.

[lokher]

Only VIA v2 json is merged to VIA github, v3 json need to be manaully loaded. The json file is in (via_json)

Please refer to below link to use it: https://www.keychron.com/blogs/archived/how-to-use-via-to-program-your-keyboard

Hey I'm closing the issue since this has to be done manually
