Related Noob Question: I'm trying to add color to my script, and I'm getting this error:

Uncaught TypeError: object.setColor is not a function
Line: 6919,col: 17

My current code is:

function main(params) {
    
    sketches = [
        square([10,2]), 
        square([3,10]),
        new polygon([
            [0,0],
            [9,0],
            [3,9],
            ],true),
        ];
        
    
    return render(sketches,params.dimension);
}

function getParameterDefinitions() {
    return [
        { name: 'dimension', type: 'checkbox', checked: false, caption: 'render in 3d?' },
    ];
}

function render(obj,dim,colors) {
    if (dim){
        extrudes =[];
        for (var i of obj){
            extrudes.push(rotate_extrude(i));
        }
        
        extrudes[0]=color(extrudes[0],"Red")
        extrudes[1]=color(extrudes[1],"Red")
        extrudes[2]=color(extrudes[2],"White")
        
        return union(extrudes);
    }
    else {
        return union(sketches);
    }
}

The only difference between the fixed version of the code and this one is the added colors after I extrude. Based on the documentation, I don't see why this doesn't work.

Thank You!

In errors, what is the blob url? Going to them just yields a 404.

I'm new to both Open(J)Scad and javascript in general, and I keep getting this error.

Uncaught TypeError: CSG.Path2d is not a constructor
Line: 97,col: 9
(blob:https://openjscad.org/f3af8c9b-afdd-46ee-ad07-40d1f04dd681)

My code is intended to create an array of 2d shapes, then render them in either 2d or 3d(using a revolve extrude) with a union().

function main(params) {
    
    sketches = [
        square([10,2]), 
        square([3,20]),
        new CSG.Path2d([
            [0,0],
            [0,9],
            [19,0],
            ],true),
        ];
    return render(sketches,params.dimension);
}

function getParameterDefinitions() {
    return [
        { name: 'dimension', type: 'checkbox', checked: false, caption: 'render in 3d?' }, 
    ];
}

function render(obj,dim) {
        if (dim){
        extrudes =[];
        for (var i of obj){
            extrudes.push(rotate_extrude(i));
        }
        return union(extrudes);
    } else {
        return union(sketches);
    }
}
