setProjection is not a function

I honestly have no idea what is causing this. I am just passing projection to the <MapLibre /> component.

<MapLibre
  onload={(event) => {
    // event.addControl(new GlobeControl(), 'top-left');
  }}
  projection={{type: "globe"}}
  bind:map
  {style}
  diffStyleUpdates
  class="relative h-full"
  attributionControl={false}
>
  {#snippet children({ map }: { map: maplibregl.Map })}
    <AttributionControl compact={true} />
    <NavigationControl />
    <GeolocateControl />
	...
 {/snippet} 
</Maplibre>

    "maplibre-gl": "5.4.0",
    "svelte-maplibre": "^1.0.0",

Hmm, my first guess would be that the package manager installed an older version of maplibre for svelte-maplibre to use despite the version specifier that you used.

This package uses a version specifier of "^4.0.0 || ^5.0.1" and I wonder if it's installed v4 for some reason.

An "npm update" or similar may help here though I recall it can be difficult to get it to update in these cases.

Can you share your lockfile? That would help to verify if this is the case.

That was it! I had to remove node_modules and use a temporary dependencyOverride.

Now another issue. ArcLayers seem to work pretty bad with the globe view. Starting in globe view doesn't show arcs at all (while ScatterplotLayer is showing correct). Switching to globe view after Mercator, results in arcs being kept but with a few artifacts, and modifying the arcs (on hover in my case) removes them again.
P.S. totally reasonable to move this to a separate issue, if this isn't a Deck.GL or maplibre-gl issue.

I don't know much about the interactions here but I would guess that deckgl isn't really aware of the projection so you might need to do something custom there to make it work.

Yeah I think so as well. When tilting the globe, the scatterplot also gets offset.
