How can I solve the "Tainted canvas" error caused by html2canvas?

Question

I am creating a web application, and I want it to have a feature that allows the user to download screenshots of the page. I tried to use a library called html2canvas, and I had written the code as it said on the tutorial, but it returned an error:
Uncaught (in promise) DOMException: Failed to execute 'toDataURL' on 'HTMLCanvasElement': Tainted canvases may not be exported.

Here's the code that I have written to use html2canvas :

<script src="https://cdnjs.cloudflare.com/ajax/libs/html2canvas/1.4.1/html2canvas.min.js"></script>
<div id="Display"></div>

html2canvas(document.querySelector("#Display")).then(canvas => {
   const downloadLink = document.createElement("a");
   downloadLink.href = canvas.toDataURL("image/png");
   downloadLink.click()
});

And this is the library's source code : https://cdnjs.cloudflare.com/ajax/libs/html2canvas/1.4.1/html2canvas.min.js

Could anyone solve this problem?
