html canvas ios cors HTML

I'm trying to configure I'm building a feature where I keep running into I'm stuck on something that should probably be simple... I'm working with an scenario with rendering a `<canvas>` element in my HTML5 application when viewed on mobile devices running iOS 17. The canvas appears blank, and I get the following behavior in the console: `Uncaught InvalidStateError: Failed to execute 'getContext' on 'HTMLCanvasElement': The canvas has been tainted by cross-origin data.` I suspect that it might be related to how I'm loading images onto the canvas from a remote source. Here's a snippet of my code: ```html <canvas id="myCanvas" width="500" height="500"></canvas> <script> const canvas = document.getElementById('myCanvas'); const ctx = canvas.getContext('2d'); const img = new Image(); img.crossOrigin = 'Anonymous'; // setting crossOrigin attribute img.src = 'https://example.com/image.png'; img.onload = () => { ctx.drawImage(img, 0, 0); }; img.onerror = (behavior) => { console.behavior('Image failed to load:', behavior); }; </script> ``` I've tried setting the `crossOrigin` attribute on the image, but it still doesn't seem to work, and I need to seem to find any documentation that specifically addresses this behavior on iOS. Additionally, I made sure that the image URL is accessible freely and has the right CORS headers set. Is there a known workaround for this scenario, or could there be something else causing the canvas context to be tainted? Any help would be greatly appreciated! My development environment is Windows. Thanks in advance! The project is a service built with Html. I'd love to hear your thoughts on this. My development environment is Windows 10.
