I'm getting this error with Kartotherian

    TypeError: Cannot read property 'length' of undefined

The code in question is

tilelive-tmstyle/index.js

Lines 178 to 186 in 0936bd4

//Layer ordering defined in style
opts.Layer = data.layers.map(function(layerId) {
for(var i = 0; i < backend.data.vector_layers.length; i++) {
var layer = backend.data.vector_layers[i];
if(layer.id == layerId) {
return layerToDef(layer);
}
}
});

Layers are explicitly defined in the project yaml but the source is a tmsource URL that doesn't resolve. I tried changing it to a tilejson URL, the same as a tmstyle that works but it had no change.
