SurfaceAppearance Normal map doesn't work

Hey everyone, I’m trying to add a normal map into a mesh to make it more detailed, but for some reason this is the result:

Any idea why and how could I solve this?

Looks like just some faces of the normal map doesn’t work???

Your normal map may be far too strong. You should also add your basecolor to the modal so it has some texture, then it might look better. A normal map should be used with a basecolor.
