TypeError: Cannot assign to read only property 'className' of object '[object SVGSVGElement]'

let url = domtoimage.toPng(document.getElementById('treeCanvas')).then(dataUrl=> { return dataUrl })
where treeCanvas is div with svg(ngx-graph component) inside it. Tried to search for this error, but it seems like this error only appeared in another library called html2canvas.

dom-to-image^latest

Ok. The problem was in fontawesome element <i class="fas fa-expand"></i>. Don't know why it happens, but just don't include it in your svg/div.
