Computer shaders kernal error

[tidal mirage]

RayTracingShader.compute: Kernel at index (0) is invalid
UnityEngine.StackTraceUtility:ExtractStackTrace ()
RayTracingMaster:Render (UnityEngine.RenderTexture) (at Assets/RayTracingMaster.cs:25)
RayTracingMaster:OnRenderImage (UnityEngine.RenderTexture,UnityEngine.RenderTexture) (at Assets/RayTracingMaster.cs:12)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)

Im using this tutorial: https://www.gamedeveloper.com/programming/gpu-ray-tracing-in-unity-part-1

some one is saying its a compiling error

Im getting error :

UnityEngine.StackTraceUtility:ExtractStackTrace ()
RayTracingMaster:Render (UnityEngine.RenderTexture) (at Assets/RayTracingMaster.cs:25)
RayTracingMaster:OnRenderImage (UnityEngine.RenderTexture,UnityEngine.RenderTexture) (at Assets/RayTracingMaster.cs:12)
UnityEngine.GUIUtility:ProcessEvent (int,intptr,bool&)```


all I know its that a kernal with an index of 0 is invalid

im trying to follow this tutorial to learn about raytracing with compute shaders: https://www.gamedeveloper.com/programming/gpu-ray-tracing-in-unity-part-1 

Im at the point were it says Try rotating the camera in the inspector. `You should see that the 'colorful sky' behaves accordingly.` but I have that error instead

kernel 0 should be the correct index (should be the first defined method in the compute shader), but you can explicily look for the right kernal/method in the shader by using https://docs.unity3d.com/ScriptReference/ComputeShader.FindKernel.html

other than that, maybe click on your compute shader asset, check the inspector and check if you find compiler errors, and if so you gotta fix those

I got it fixed some howw
