gmod methlab 2 error

[zeros_methlab02_1.2.5] addons/zeros_methlab02_1.2.5/lua/entities/zmlab2_item_palette/cl_init.lua:21: attempt to index field 'Palette' (a nil value)

what can i do?

As I know, the specific error message suggests that there is an issue with the 'Palette' field in the "cl_init.lua" file of the "zmlab2_item_palette" entity.

I think you should double-check that you have any required dependencies or supporting addons installed. Some addons may rely on other addons to function properly. uno online
