Selecting a element by it’s css selector

I’m trying to select an image element using its style selector. I wrote the line of code in Python but I’m having problems translating it to JavaScript. Here’s my attempt so far.

if driver.find_element_by_css_selector("img[style='object-fit: cover;']") is not None:
        download_url = driver.find_element_by_css_selector("img[style='object-fit: cover;']").get_attribute('src')

And here is my js attempt.

let imageArr = []

for(let post of posts) {
    await page.goto(post)
    await page.waitForTimeout(6000)

    if (await page.type("img[style='object-fit: cover;']") !== null) {

        const image = await page.evaluate(() => {
            document.querySelectorAll("img[style='object-fit: cover;']").forEach(img => {
                let imageUrl = img.getAttribute('src');
                imageArr.push(imageUrl)
            })
        })
    }
}
