write_image Kaleido failed to generate static image

[neo-escieur]

On Windows:
with this in Cargo.toml:

[dependencies]
plotly = { version = "0.12.1", features = ["kaleido", "kaleido_download"] }
rand = "0.8.5"
rand_distr = "0.4.3"

and this code :

use plotly::{
    color::{NamedColor},
    common::{ Marker },
    layout::{Layout, BarMode},
    Histogram, Plot, ImageFormat
};
use rand_distr::{Distribution, Normal};
fn sample_normal_distribution(n: usize, mean: f64, std_dev: f64) -> Vec<f64> {
    let mut rng = rand::thread_rng();
    let dist = Normal::new(mean, std_dev).unwrap();
    let mut v = Vec::<f64>::with_capacity(n);
    for _idx in 1..n {
        v.push(dist.sample(&mut rng));
    }
    v
}

fn main() {
    let samples1 = sample_normal_distribution(500, 0.0, 1.0);
    let trace1 = Histogram::new(samples1)
        .name("trace 1")
        .opacity(0.5)
        .marker(Marker::new().color(NamedColor::Green));

    let samples2 = sample_normal_distribution(500, 0.0, 1.0);
    let trace2 = Histogram::new(samples2)
        .name("trace 2")
        .opacity(0.6)
        .marker(Marker::new().color(NamedColor::Red));

    let mut plot = Plot::new();
    plot.add_trace(trace1);
    plot.add_trace(trace2);

    let layout = Layout::new().bar_mode(BarMode::Stack);
    plot.set_layout(layout);
    plot.write_html("out.html");
    plot.write_image("testx", ImageFormat::PNG, 800, 600, 1.0);
}

the file out.html is ok but testx.png is created but empty.

this is the error:

Kaleido failed to generate static image for format: png.
Kaleido stderr output:
[0108/174710.543:WARNING:resource_bundle.cc(405)] locale_file_path.empty() for locale
[0108/174710.605:WARNING:headless_browser_main_parts.cc(83)] Cannot create Pref Service with no user data dir.

is there a way to make this working on windows ?
