DOM element to image generates only white image

I’m using html2canvas to create images from the DOM element.

The code looks like this.

    const node = document.getElementById('domElement') 
    html2canvas(node, {
      windowWidth: node.scrollWidth,
      windowHeight: node.scrollHeight,
    }).then(canvas => {
      const image = canvas.toDataURL()
    })

But its only rendering an image that is fully white. The image size (l*b) is accurate.

enter image description here

But when I try to render the image of the full body it shows the image but with blank white screen on top.

i.e. when,

    const node = document.body 

enter image description here

How will the elements be added properly and not the blank white screen on the image?

The code is inside an antd design modal.

This statement solved my problem.

window.scrollTo(0, 0)

The final code looks like

window.scrollTo(0, 0)
const node = document.getElementById('domElement') 
html2canvas(node, {
  windowWidth: node.scrollWidth,
  windowHeight: node.scrollHeight,
}).then(canvas => {
  const image = canvas.toDataURL()
})
