spotipy: recommendations() requests.exceptions.HTTPError

I have the following code:

import spotipy
from spotipy.oauth2 import SpotifyOAuth

username = 'XXX'
client_id = 'XXX'
client_secret = 'XXX'
redirect_uri = 'http://localhost:8888/callback/'
scope = 'user-top-read user-read-recently-played playlist-modify-public playlist-modify-private'

sp = spotipy.Spotify(auth_manager=SpotifyOAuth(client_id=client_id, client_secret=client_secret,
                                               redirect_uri=redirect_uri, scope=scope, username=username))

print(sp.recommendations(
        seed_tracks=['spotify:track:7cm50Lw03k6VvRauJtkyTj', 'spotify:track:3zwMVvkBe2qIKDObWgXw4N',
                     'spotify:track:0KRYCBwIpWYFNrXOmXbyUh', 'spotify:track:5BK0uqwY9DNfZ630STAEaq',

Once again I tried to find out what causes this and by simplifying my code step by step, I found out that adding a from flask import Flask/import flask in the same file as spotipy causes this issue (even if Flask is never used in any way).

So this minimal example breaks for me both during development and on the main server:

import spotipy
from spotipy import SpotifyClientCredentials
from flask import Flask
from config import spotify

crm = SpotifyClientCredentials(**spotify)
sp = spotipy.Spotify(client_credentials_manager=crm)
del sp

I am using flask 2.0.2 and have absolutely no clue why this would happen.

Why don’t you just catch the error as I did here? Using if requests.Session is a terrible idea because who knows what the __bool__ method will return. If you’re trying to check if it’s not None, then do so explicitly: if requests.Session is not None.

as it is not properly closed and therfore a new TCP connection is opened for every request instead of reusing them.

If requests.Session has somehow been assigned to None (which is what causes this exception), then self._session won’t be properly closed regardless of whether you use your updated version of __del__ or the current version.

The only way to ensure that the session is properly closed in the __del__ method is to find the underlying reason that requests.Session is being assigned to None.
