The alpha_high argument to set liquid-alpha values was below the minimum of roughly 0.025 (1638/65535 in u16 units). Raise alpha_high in the sudo_set_alpha_values call; current values are in the AlphaValues storage per netuid.
Declared by the SubtensorModule pallet; it classifies to the semantic code invalid_argument.
