Save error

[tpatgm]

Hello,
I'm new user of ConstrcutiveGeometry.
WhanI run the sphre_cube example, there is the following error with save.
What am I doing wrong.
Thank you for your support
Thierry

julia> save("sphere_cube.png", u)
Errors encountered while save File{DataFormat{:PNG}, String}("sphere_cube.png").
All errors:

MethodError: no method matching save(::File{DataFormat{:PNG}, String}, ::ConstructiveGeometry.ConstructedSolid{:union, Vector{ConstructiveGeometry.AbstractGeometry{3}}, 3})

The actual plotting is done by CairoMakie, so this is how it should be done:

using ConstructiveGeometry, FileIO, CairoMakie
save("/tmp/a.png", sphere(10))

(I guess I could add an error message when no Makie backend is loaded, but currently I don't know how to detect this).

Thank you for your answer,
here is the error message for save (using julia 1.7 on windows 10)
