A 3D-vector is expected both after location and look_at.
The Spline_Trans() macro returns a transformation, not a 3D-vector.

If you want to apply a transformation to a 3D-vector, you can do it like this:

#declare SplineTransform = Spline_Trans(Spline_1, 0.0, y, 0.03, 0.95)
#declare p0 = <0, 0, 0>;
#declare p0_Transformed = vtransform(p0, SplineTransform);
