Unclear error when running an animator without an `init`

[jon-wurtz]

When running the following code snippet through an animator (note that I have commented out the init)

@move
def foo_move():
    zone = spec.get_static_trap(zone_id="traps")
    src = grid.sub_grid(zone, [0], [0])
    dst = grid.sub_grid(zone, [1], [1])
    waypoints = ilist.IList([src, dst])
    
    # init.fill([spec.get_static_trap(zone_id="traps")])
    move_by_waypoints(waypoints, True, True)

raises an error when run through an animator
