Describe the bug
TypeError: 'dict' object is not callable while running 'example/apps.py'

Your code
app.py

Expected behavior
should return dict like response

Output

TypeError: 'dict' object is not callable
The view function did not return a valid response. The return type must be a string, tuple, Response instance, or WSGI callable, but it was a dict.

Environment:

cachelib==0.10.2
certifi==2019.3.9
chardet==3.0.4
charset-normalizer==3.0.1

Additional context
soltuion:

from flask import jsonify
''
"jsonify" whenever a dict is returned
for example:
``
@app.route('/playlists')
def playlists():
cache_handler = spotipy.cache_handler.FlaskSessionCacheHandler(session)
auth_manager = spotipy.oauth2.SpotifyOAuth(cache_handler=cache_handler)
if not auth_manager.validate_token(cache_handler.get_cached_token()):
return redirect('/')

spotify = spotipy.Spotify(auth_manager=auth_manager)
return jsonify(spotify.current_user_playlists())
