Remove extruded edges from custom Shader graph

Beastman632

Hey guys

I made a Sprite lit shader graph that draws an outline around a sprite, but for some reason it creates these extruded edges around the sprite. How do I solve that? The default shader Sprite-Lit-Default doesn't seem to have the same issue.

This is the Sprite-Lit-Default shader

This is my custom shader

How do I get rid of those extruded edges? Thanks in advance
