QML Mapbox with custom sprite

[i.n.g.o.]

Hi.

I am struggling using a custom sprite with Mapbox.
My custom sprite and json descriptions are available online, i added this

MapParameter {
    type: "image"

    property var name: "mySprite"
    property var sprite: "https://url-to-sprite"
}

and later use it in a style-layer with a layout

MapParameter {
    id: mylocationlayout
    type: "layout"

    property var layer: "myLocationLayer"
    property var iconImage: "myicon"
}

it gives me:

[ ERROR ]  "{unknown}[Style]: Failed to load sprite: HTTP status code 404"

ok, it cannot find the sprite, but why? and how to make it work?
the same url is also used in the mapbox-style itself...

i am not sure with that "sprite" property, and also tried "url", with the same result.

thanks for any help

I ended up not using online-sprites but load the sprites in QML:

MapParameter {
    type: "image"
    property var name: "mySprite"
    property var sprite: ":/path_to_iamge_in_resources"
}

using it in a layout like this:

MapParameter {
    type: "layout"
    property var layer: "myLayer"

    property var iconImage: "mySprite"
}
