mainImage for using depth does not work

[aliiscript]

the regular void mainImage(const in vec4 inputColor, const in vec2 uv, out vec4 outputColor); works fine but I want to use the one that includes depth ( void mainImage(const in vec4 inputColor, const in vec2 uv, const in float depth, out vec4 outputColor); ) as a parameter but get this error: 'e1MainImage' : no matching overloaded function found . I assume it because that function doesn't exist but not sure how to fix, any help would be appreciated.

Make sure your effect is using EffectAttribute.DETPH:

import { Effect, EffectAttribute } from "postprocessing";

class MyEffect extends Effect {

	constructor() {

		super("MyEffect", fragmentShader, {
			attributes: EffectAttribute.DEPTH
		});

	}

}
