Problem with alpha in shader graph

Hi !
I wanted to make a shader that allows sprites to cast shadows. I’m using URP in Unity 2020.2
I have a problem : the shader makes my sprite semi-transparent on brighter areas (like the skin).

Here is a video of the problem and my shader graph : link to youtube video

Thanks for your help !

Ok I resolved my problem.

I changed the shader from Lit to Unlit and I changed blend mode from Multiply to Alpha.
