I had the same problem today and I am using Windows 7. Windows 7 uses powershell 2.0 so I upgraded it to 5.1, you can upgrade it from here - https://docs.microsoft.com/en-us/powershell/scripting/install/installing-windows-powershell?view=powershell-6

Upgrading this solved my problem. I found this solution from here - https://github.com/aspnet/AspNetCore.Docs/issues/14863

Upgrade Powershell to 5.1

This is the link from where you can download according to your system requirement.

I have had the same error, everything was correct and there was no problem with the packages, nor problems with PowerShell. What happened was that I copied the script that I had done before from GitHub and pasted it into the Visual Studio package management console, without knowing that when I copied this from GitHub I copied a strange character that was invisible in the console, but which was causing the error.

Be careful when copying and pasting code or scripts because this can happen to you.

You should enable the options allowTain As follow and make sur that the Access-Control-Allow-Origin header is enable for your site

 function downloadDiv(divid) {
        html2canvas(document.getElementById(divid), {allowTaint : true}).then(function (canvas) { 
            $("#previewImg").append(canvas);
            var anchorTag = document.createElement("a");
            document.body.appendChild(anchorTag);
            // document.getElementById(divid+"2").appendChild(canvas);
            anchorTag.download = "Visitor_"+divid+".png";
            anchorTag.href = canvas.toDataURL();
            anchorTag.target = '_blank';
            anchorTag.click();
        });
    }
