I’m using Python requests to get some info from Spotify API, After some requests, I encountered the 429 error, which indicates that the request limit has been exceeded. It is written in the Spotify document that when you encounter this error, there is a Retry-After in the response header that you have to wait for that amount of time and request again, but the response header that I receive does not have such a thing.

here is the code:

url = f'https://api.spotify.com/v1/audio-features/{track_id}'
res = requests.get(url, headers=self.headers)
if res.ok:
    return res.json()
if res.status_code == 429:
    print("------------- 429 ----------------")
    print(res.headers)
    return None

here is the response header:
