Can't change page background using code?

[miguel-galvez]

I’ve tried changing the page background with this:

$w("#page").background.src = "https://image.tmdb.org/t/p/w1280" + movie.backdrop_path;

But background is underlined with a wavy red line indicating the following error: ‘background’ does not exist on ‘#page’.

What am I doing wrong?

use $w(“Document”).background.src
