I am trying to execute the following script on Julia 1.6.0

```julia
#select packages
using VegaDatasets
using DataVoyager
using VegaLite

# load dataset
data = dataset("iris")
#display data
vscodedisplay(data)
v=Voyager()

```

and I get the following errors:

```julia

I tried the same sort of thing with Juan Klapper’s Youtube video of Vegalite on a Pluto session, and for:

```julia
begin
	using VegaDatasets, VegaLite
	using Random, Distributions, DataFrames
end

begin
	Random.seed!(12)
	Independent=0:0.1:9.9 #Using a Unitrange object
	dependent=Independent .+ randn(length(Independent));
end

@vlplot(
	:point,
	x = Independent,
	y = dependent
	)

```

in three cells, the plot is not displayed; the error is

```julia
Failed to show value:

Julia 1.6 on Windows has a breaking change how it handles artifacts that broke NodeJS.jl and every single package that depends on that… I’m trying to work around that now, hopefully it will be fixed soon.

@davidanthoff , Thanks. I got Vegalite to behave on VS Code, but it is broken on Pluto. And DataVoyager is broken on VS Code. So, stuff still works, but I’ll keep a lookout for a fix. Do you have a error tracker that I can follow?

That all makes sense: when you use VegaLite.jl inside VS Code it doesn’t need the NodeJS functionality. DataVoyager.jl depends on Electron.jl, and that was also broken by the change in artifacts in Julia 1.6…

At this point I’ve tagged new versions of NodeJS and Electron, and so it might all work again if you update things. I don’t have time today to test all the downstream packages, but fingers crossed it might all be ok now.

I tried a package update. Still cannot spawn electron from VS Code. Do I need to update a particular tag out of the mainstream?

Could you post the version of NodeJS.jl that is in your environment?

It is 1.1.2  
Should I do  
Pkg.add NodeJS@1.1.3 instead?

Tried and seems like 1.1.2 is the latest.

No, 1.1.2 is the latest version… Hm… Could you try and look what permissions in Windows the file `C:\Users\XXXXXX\.julia\artifacts\345df2b824d1eacefab89d560a9e929ff24c0537\node.exe` has on your system?

Full control for myself, system and Administrators. But the properties shows folder is read-only.

Ah, I know what was going on! Just tagged a new DataVoyager version, can you update and try again?

Works now in VS Code. Thanks much./K

Update: Also in Pluto.
