502 Error while searching SoundCloud playlists

import soundcloud

client = soundcloud.Client(client_id='mykey')
page_size = 10
tracks = client.get('/tracks', q='lorde',limit=page_size)
users = client.get('/users', q='lorde',limit=page_size)
sets = client.get('/playlists',q='lorde',limit=page_size)

      

        
        
        
      

    

In the above Python code extract, while tracks and users are working fine, the last line returns the following error.

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "soundcloud/client.py", line 130, in _request

For phrases that return fewer results, such as "banana phone", the query works fine (albeit a little slow). However, an error is returned for a search that returns more results. This search also works on the website, so I guess it has something to do with the fact that I am using soundcloud-python. What am I doing wrong and how can I resolve this error?
