Post-process effects don't work in URP 2D

Unity Engine
1

I tried to make a post-processing effect in a pure universal 2D template based on this guide
guide link

But I get a black screen and the error “Trying to use an invalid resource (pass FullScreenPassRendererFeature)”
It works in universal 3D template. It also works with the render graph disabled.
Why doesn’t this work?

Same problem here following the custom full screen tuto on Unity documentation. I’m also using URP 2D.
