System Information
Operating system: Linux-5.4.0-77-generic-x86_64-with-glibc2.27 64 Bits
Graphics card: GeForce GT 630/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 390.143

Blender Version
Broken: version: 3.0.0 Alpha, branch: master, commit date: 2021-06-23 22:10, hash: f7fbb518c8
Worked: (newest version of Blender that worked as expected)

Short description of error
I assume that the line primitive can't be scaled because 0 times something stais 0, right? Is there a solution for this problem? The goal was to use the z-values to scale the points accordingly, but is doesn't work as hoped (please see picture)

Thanks for the report. radius is the attribute on curves used in this case, not scale from the point scale node. It's too bad these attributes aren't unified I suppose, but I don't think this is a bug, and there would be other downsides to making that change.
