The problem is variable "ctx" remains null after declaring it equal to "ctx = canvas.getContext('2d');" while variable "canvas" stores the following html dom element:

`<canvas data-engine="three.js r172" width="1140" height="912" style="display: block; width: 570px; height: 456px;"></canvas> `

Further context of the decribed problem above is this erroneous null is declared and logged out during function initHUD() and drawSymbol() of seperate modular file hud.js. Further consider that variable "canvas" storing the dom refrence is passed in as parameter canvasElement such as initHUD(canvasElement) where canvas = canvasElement. It may be inmportant so lastly, canvasELement originates from initialize() where "renderer = new THREE. WebGLRenderer" and "canvasInit = renderer.domElement". If you made it this cosider the overarching goal is to line up a heads up display within the inside border of the webGLRenderer.

navbox.js (main)

function initialize();

hud.js (module)

export function initHUD(canvasElement) export function drawSymbol()

Consider the following code where the ctx variable is declared in hud.js however also consider navbox.js where canvasElement originates:

hud.js...
`let symbolImg = null;
 let canvas = null;
 let ctx = null;
    export function initHUD(canvasElement) {
    console.log("intiHUD TEST canvasElement:" , canvasElement);
    canvas = canvasElement;
    if (!canvas) {
        console.error("Canvas element is null in initHUD");
        return; // Important: Exit if canvas is null
    }
    console.log("canvas in initHUD" , canvas);
//  IMPORTANT:  Delay getting the context until the next frame
    requestAnimationFrame(() => {
        console.log("REQUEST ANIMATION FRAME!!!");
        try {
            ctx = canvas.getContext('2d');
        } catch (error) {
            console.error("Exception while getting context:", error);
            ctx = null;
        }

        console.log("Context in ANIMATION FRAME:", ctx);

        if (!ctx) {
            console.error("Failed to get canvas context in initHUD");
            return;
        }

        console.log("Context:", ctx);

        symbolImg = new Image();
        symbolImg.src = '/images/pen-to-square-solid.svg';
        symbolImg.onload = () => {
            drawSymbol();
            window.addEventListener('resize', resizeCanvas);
            resizeCanvas();
        };
        symbolImg.onerror = (error) => {
            console.error("Error loading image:", error);
        };
    }); // End of requestAnimationFrame
}`


navbox.js...
    `renderer = new THREE.WebGLRenderer({ antialias: true , alpha:true 
     }); 
     console.log("1. WebGLRenderer created");
     renderer.setSize(width, height);
     console.log("2. Renderer size set");
     renderer.setPixelRatio(window.devicePixelRatio);
     console.log("3. Pixel ratio set" , window.devicePixelRatio);
     renderer.outputEncoding = THREE.sRGBEncoding;
     console.log("4. Output encoding set");
     renderer.alpha = true;
     console.log("5. Alpha set");

     console.log("renderer.domELemenent" , renderer.domElement);
     contenedor.appendChild(renderer.domElement);
     canvas = renderer.domElement; // Store the canvas element!
     initHUD(canvas); // Initialize HUD *after* canvas is created`
