Why is Higgsas's Mesh Face Divider not working?

I am using blender version 4.3 and got the 4.3 geometry nodes tool kit. In his latest updates, he mentioned that the mesh face divider now works with n-gon faces and triangular faces. I turned a grid (I randomly deleted some faces) into a curve and back to a mesh (before using fill curve set to n-gon, the triangle option worked with the mesh face divider like he said it would, but for some reason the n-gon option is not working). As you can see from the pictures the plane did not subdivide like I wanted it to.

This group node is throwing an error, what does it tell you?

I didn’t even notice that. But it is weird because it says “input geometry has unsupported type: Mesh”.

This is the group nodes. I don’t get why it says that though.

fill curve outputs a mesh.

Thanks for that, I did not even notice since they are the same color and it did not have the red line when I plugged it in. I got rid of the fill curve and join geometry node in the group. The error is gone, but the mesh face divider still does not work.
