Spotipy requests taking forever

Question

I have been using Spotipy to get song data from a list of songs. It was working before, but suddenly the spotipy requests stopped finishing and the code is stuck. Any ideas what is going on?

def get_song_uri(row):
    song = row['song']
    artist = row['artist']
    data_list = []
    #Get song uri
    print('search1')
    res1 = sp.search(q='track:'+song+' artist:'+artist[:5],type='track')['tracks']['items']
    print('search2')
    if len(res1) == 0:
        uri = pd.NA
        for i in range(0,10): # Create a 10 feature vector of NA's
            data_list.append(pd.NA)
    else:
        uri = res1[0]['uri']
        print('b')
        res2 = sp.audio_features(uri)[0] # Create a 10 feature vector of all the features (including URI)
        data_list=[uri, res2['danceability'], res2['energy'], res2['loudness'], res2['speechiness'], res2['acousticness'], res2['instrumentalness'], res2['liveness'], res2['valence'], res2['tempo']]
    print('Done')
    return data_list

The code prints 'search1' but not 'search2', so I know it is stuck on the request.
