Error handling of appendScene function

I am trying to programmatically use the “appendScene” function to add several (say 10) glTFs to my scene. Like so:


arr[] = {one.gltf, two.gltf,..., ten.gltf};
for(var i=0;i<10;i++){
appendScene(arr,arr, false, false, function() {}, function() {}, function() {console.log("Error")});
}


If some glTFs don’t load, I’m printing “Error” to the console.
This works fine.
But is there a way to print which glTFs, in particular, are missing/erroneous?
