Hover shader on text doesn't work in godot 4?

Question

I'm getting no errors, but for some reason a hover shader I used in godot 3 doesn't work anymore. Does anyone know why?
This is the code:

shader_type canvas_item;

uniform float height = 5.0;
uniform float speed = 5.0;

void fragment() {
	VERTEX.y += height * sin(speed * TIME);
}

godot v4.0.3.stable

Answer 1

are you sure you had the ...

void fragment() {
	VERTEX.y += height * sin(speed * TIME);
}

... in the fragment section?

void vertex() {
	VERTEX.y += height * sin(speed * TIME);
}

.. makes it wobble up and down.
Is this what you wanted?

Answer 3

The shader is supposed to make the text move on the y axis, but the text doesn't move.
