Unable to render parametric equations in Manim

Question

When I attempt to render the parametric equations: x = 0 y = t z = t, Manim does not plot them.

Is something wrong with manim's installation on my computer, something wrong with my code, or something else I may have missed? Here is my code:

from manim import *

class Tute1(ThreeDScene):
    def construct(self):

        axes = ThreeDAxes(
            x_range=[-6, 6, 1],
            y_range=[-125,125, 25],
            z_range=[0,250, 25],
            axis_config={"include_numbers": True}
        )

        graph = ParametricFunction(
            lambda t: np.array([
                0,
                t,
                t
            ]), t_range=[0, 250], color=RED
        ).set_shade_in_3d(True)

        self.add(axes)

        self.move_camera(phi=60 * DEGREES)
        self.move_camera(theta=-45 * DEGREES)

        self.play(Create(graph))
        self.wait()
    
        self.begin_ambient_camera_rotation(
            rate=PI / 10, about="phi"
        )  
        self.wait(5)
        self.stop_ambient_camera_rotation()`

I have tried a number of other plotting methods, but I need to use ParametricFunction.
