The following throws an UndefVarError:

error("Cannot determine a colorrange automatically for single number color value $intens. Pass an explicit colorrange.")

Should reference intensity rather than intens?

            plot[:colorrange][] isa Automatic &&
-                error("Cannot determine a colorrange automatically for single number color value $intens. Pass an explicit colorrange.")
+                error("Cannot determine a colorrange automatically for single number color value $(intensity[]). Pass an explicit colorrange.")

Ah yes if there's an intensity value around there then it's supposed to reference that. Whatever holds the 1 from your example

Hi, having the same issue here.

[pitipatw]

Quick fix is to add
colorrange=0:1 into the lines!()'s argument, and it should run :)

This throws an error nowadays
