Error when opening zipfiles requests. zipfile.BadZipFile: File is not a zip file

[Tyarel8]

After attempting to donwload and extract a zipfile using httpx

rz = httpx.get(url)
with zipfile.ZipFile(BytesIO(rz.content)) as z:
         z.extractall(DOWNLOAD_PATH)

it throws the following error zipfile.BadZipFile: File is not a zip file

However, using the exact same code but with the requests module works as intended

rz = requests.get(url)
with zipfile.ZipFile(BytesIO(rz.content)) as z:
         z.extractall(DOWNLOAD_PATH)
