                                               redirect_uri=redirect_uri, scope=scope, username=username))

There's also a pretty simple way to debug error you're getting in the SpotifyAuthBase.__del__. The second argument passed to isinstance() is requests.Session, which is a type. More specifically, it's a class. The fact that the error message suggests that it's not a type means that this name is somehow being reassigned to some other object that's not a type. Change the __del__ method as follows to find out what this name is being reassigned to (and what its type is):

def __del__(self):
    """Make sure the connection (pool) gets closed"""
    try:
        if isinstance(self._session, requests.Session):
            self._session.close()
    except TypeError as error:
        print(error)
        print(
            f"`requests.Session`: {requests.Session}. "
            f"type of `requests.Session`: {type(requests.Session)}"
        )

I'm still curious about the cause of the error in the __del__ method. In theory, this should be unrelated to the issue with the recommendations endpoint. This error has come up in multiple issues, yet I've been unable to reproduce it. Can you try to reproduce it with the modified __del__ method that I posted?

I also was unable to reproduce it. I wasn't able to figure out how to get around read-only permissions (I installed with pip) in PyCharm, and when I pulled directly from this repo instead, I couldn't compile the code because of a ModuleNotFound error for the cache_handler file, even though the module was clearly there. Instead, I took the code you wrote and replaced self._session with sp. When I ran the try-except at the top of the file, it didn't work, but when I instantiated the sp object inside my main method and ran the try-except there, the error went away. This isn't ideal, since now I have to pass the sp variable into every one of my functions, but it's not too big of a deal. For clarification, I had this:

# these are declared at the top of the file, outside of a function
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))
# running the try-except here didn't catch the exception

def main():
   sp.recommendations(...)

and now I have this:

# no variables declared at the top of the file

def main():
  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))

  sp.recommendations(...)

which works fine. If you know how to get around the read-only permissions in PyCharm, I'd be happy to try to reproduce it with the __del__ method you wrote. I did some research to no avail--it prompts me to change the read-only permissions, only to tell me each time that it was unable to execute that request.

What did you mean when you said that you "replaced self._session with sp"? If you're having trouble reproducing the error, then make sure you change as little as possible. Only change the __del__ method as I described above. Make the same exact call to the recommendations endpoint that you did in the original code (i.e., with the incorrect number of seed tracks/artists).

Okay, the sudo command worked. I ran the __del__ method you wrote with the same call to recommendations as in the original post (the incorrect one), and got this:

In case it helps, this error also comes up whether I call recommendations() or not. If I change the main() method to do nothing at all (just pass), it still prints:

since I'm still instantiating sp at the top of the file. The difference comes from whether sp is instantiated at the top of the file, or inside the main method. If it's inside the main method, there's no error, and if it's outside, there's this error.

At the beginning of your code, import requests and print(requests.Session). See if it's None.

Just FYI: I have the same issue and absolutely no clue what is going wrong. I updated a lot of dependencies in my application (including requests and spotipy from 2.16.1 to 2.18.0, but quickly downgrading both doesn't seem to fix it) and since then I get the mentioned exception on every run (both in oauth2.py and in client.py).
type(requests.Session) prints <class 'NoneType'>

I updated the code to

if requests.Session and isinstance(self._session, requests.Session):
    self._session.close()

which of course isn't a solution (as it probably breaks the Session), but as my script is not running permanently, but as a scheduled task with very few requests per run, I doubt it will hurt that much.

Sorry for being vague: I mean by that this change might mean that requests use it's Session class anymore as it is not properly closed and therfore a new TCP connection is opened for every request instead of reusing them.
But this is just a blind guess.

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.

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.

@dieser-niko Good question. I checked again and it seems like I have been including the workaround of modifying del ever since. But I just tested removing it and it still seems to work, so I guess maybe some flask update fixed it?

Either way I also can't reproduce it anymore.
