I already read this post but it doesnt worked for me: Extract content of <script> with BeautifulSoup

Answer

There are different things to point out:

1. Instead of find_all() that would return a resultset use find(), cause there is only one script tag the would match.

2. Intstead of converting the tag and its content into a str() use .text to extract the content.

3. Main issue is that you have to replace all " in your extracted text, cause per se it is no valid json if you print, it would look like:

   '{"@context":"http://schema.org","@type":"Product","aggregateRating"...'

Fix:

paragraphs = json.loads(soup.find('script', type='application/ld+json').text.replace(""", """))

Short code:

url = 'https://www.zalando.de/nike-sportswear-blazer-mid-77-jumbo-unisex-sneaker-high-whiteblacksailteam-orange-ni112n02s-a11.html'
headers = {'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/97.0.4692.71 Safari/537.36'}
req = requests.get(url, headers=headers)

soup = BeautifulSoup(req.text, "html.parser")
jsonData =  json.loads(soup.find('script', type='application/ld+json').text.replace(""", """))

JSON:
