You might be running into a sequencing problem e.g. the component is
being created prior to the assets, hence you're getting a null here. Why not
just get the asset during the render method of the component? Not sure
that'll work, but there's really no reason your logic has to be in the
constructor so I'd definitely try moving it to render.
