Figma API: Image export problem

I created a simple component. And created a new image based on its instance.

Next, I want to get the image using REST Api. Unfortunately the component instance doesn’t render correctly.

"id": "0:1",
"name": "Page 1",
"type": "CANVAS",

https://api.figma.com/v1/images/q7Yv***6ex?ids=0:1&scale=4

I expected to see the whole page.
