Cannot save WorldClim Elevation data to .tif

When I try to use savecube to resave the WorldClim elevation to tif I get the following error:

using YAXArrays
using RasterDataSources
elevpath = getraster(WorldClim{Elevation},:elev, res="30s")
elev = Cube(elevpath)
zarrpath = tempname() * ".zarr"
julia> savecube(elev, zarrpath)
ERROR: Could not determine output projection from attributes, please specify userproj

Some type information was truncated. Use `show(err)` to see complete types.

Start with savecube in YAXArrays.Datasets at Datasets.jl:617-637, then trace the getproj and create_dataset calls shown in YAXArrayBase's archgdal.jl at lines 127-157. Reproduce the WorldClim elevation example and clarify the expected TIFF output versus the zarrpath used in the report; done means saving the elevation data completes without the projection error.
