Script error in Mixxx 2.5 when using Traktor Kontrol S4 MK2

[VamLykTan]

Bug Description

Hello dear community,

I received Mixxx 2.5 today via Ubuntu update and when I started it I received the following message.

The error message contained gives me the following information.

Uncaught exception: file:///usr/share/mixxx/controllers/Traktor-Kontrol-S4-MK2-hid-scripts.js:696:
TypeError: Passing incompatible arguments to C++ functions from JavaScript is not allowed.

Backtrace: @file:///usr/share/mixxx/controllers/Traktor-Kontrol-S4-MK2-hid-scripts.js:696
@file:///usr/share/mixxx/controllers/Traktor-Kontrol-S4-MK2-hid-scripts.js:714

I hope this bug will be fixed as soon as possible.

The current version is attached in the following screenshot.

Thanks for your report.

Until this has been debugged and fixed you can simply deactivate the line that calls the broken function pointlessLightShow(). It's line 714 in Traktor-Kontrol-S4-MK2-hid-scripts.js
A links to mapping files are in the controller's preferences page.
Either you edit the script file in place as superuser (will be overridden with next Mixxx update) or copy both the Kontrol S2mk2 xml and js file to controllers in your user data / settings directory (on Ubuntu it's ~/.mixxx/).

Could you try to change line:

mixxx/res/controllers/Traktor-Kontrol-S4-MK2-hid-scripts.js

Line 682 in 91ea847

var packets = [Object(), Object(), Object()];

to
var packets = [[], [], []];
