2D Outline Shader working in Node Preview But not when rendering

Hi guys, I wanted to do a 2D outline shader for my project using shader graph. The preview in the last shader node before the master node is just what i want.

But the final preview is something else. There is no outline, and when i change the outline thickness value there are weird changes inside the sprite not outside.

• I checked if i had enough space in my sprites.

• I have set the used sprites to full rect.

• I am using the latest shader graph version.

Any help or hint to what i might have done wrong is greatly appreciated!
