open .zarr file as a Cube fails

[lazarusA]

Since I'm trying to open/load a Zarr file into a Cube, I'm opening this issue here, although it seems that this is related to DiskArrayTools.

using Zarr, YAXArrays
urlStore = "https://storage.de.cloud.ovh.net/v1/AUTH_84d6da8e37fe4bb5aea18902da8c1170/uc3/FireCube_time1_x1253_y983.zarr"
cube = Cube(urlStore)
#g = zopen(urlStore, consolidated=true)

outputs the error:

ERROR: MethodError: no method matching Union{Missing, Float32}(::Float64)
Stacktrace:
 [1] DiskArrayTools.CFDiskArray(a::ZArray{Union{Missing, Float32}, 3, Zarr.BloscCompressor, Zarr.ConsolidatedStore{Zarr.HTTPStore}}, attr::Dict{String, Any})

doing

g = zopen(urlStore, consolidated=true)

works.

This seems to be a problem in the handling of missing values in DiskArrayTools. I added a pull request to DiskArrayTools.jl with which your example cube is opened.

wow! yes. This seems to work. I can open and download the data successfully with that PR.

I'm still getting this issue on the latest release. The issue on DiskArraysTools is still open. https://github.com/meggart/DiskArrayTools.jl/pull/10

I just tested again these examples. I'm still getting the same error as before:

ArgumentError: invalid index: nothing of type Nothing
