How to make a loading icon with an svg file p5.js (Access to Image at '' from origin 'null' has been blocked by CORS policy: Invalid response. Origin 'null' is therefore not allowed access

p5.js Beginners

idk how to load the svg file. When i try i get a “Access to Image at ‘’ from origin ‘null’ has been blocked by CORS policy: Invalid response. Origin ‘null’ is therefore not allowed access.”
If svg filetypes aren’t supported can someone at least tell me where I can convert the file into a gif or sequence of png’s (and use that to make a loading icon)?
Here is the svg loader im trying to use.

var img;
var loadicon;
var loading = true;

function doneLoading(){
 loading = false;
}

function setup(){
 var cnv = createCanvas(windowWidth, windowHeight);
 cnv.style('display', 'block');
 cnv.class('cnv');
 noStroke();

 //have to use link to load image not a local file
 img = loadImage('https://raw.githubusercontent.com/petercpark/Mindless-Rubik-s-Cube-Solution/master/rubikscube.png', doneLoading);
 loadicon = loadImage('loading.svg');
}

function draw(){
 if(loading){
 image(loadicon, width/2, height/2);
 }

 else {
 //stuff that i run
 }
}

How are you running this code? What url are you using to access your sketch?

Please fix your title. The title is to summarize your problem. You write a description in the body of your message.

Your loading logic is backwards. It should be false when init and set to true when doneLoading() is called.

If you are using chrome try using firefox.

does it work in firefox?

Yes it does but I wanted it to also run in Chrome so I changed the svg into a gif somehow and put it on a Github repository and used the link of the gif image from Github to host the image file and load it into my site.
