Something wrong with custom function GetLighningInformation in Shader Graph

Question

void GetLightingInformation_float(out float3 Direction, out float3 Color,out float Attenuation)
{
    #ifdef SHADERGRAPH_PREVIEW
        Direction = float3(-0.5,0.5,-0.5);
        Color = float3(1,1,1);
        Attenuation = 0.4;
    #else
        Light light = GetMainLight();
        Direction = light.direction;
        Attenuation = light.distanceAttenuation;
        Color = light.color;
    #endif
}

MainLight.hlsl

I think there's something wrong with code or unity version (unity 2021.3.4f1)

If I gonna don't using this function everything will be ok, but if I use it, I get error like this:

Shader error in 'Master': 'GetLightingInformation_float': output parameter 'Direction' not completely initialized at Assets/Shaders/MainLight.hlsl(1) (on d3d11)
