I'm using the MusixMatch API to get a list of tracks given a musixmatch assigned album id. The album id I'm using is 20903197 and I have validated it works. https://playground.musixmatch.com/#!/Track/get_album_tracks_get plug that into album_id field
However, when I try calling it using their python sdk I'm getting a response with None for all the attributes but returning 200 response. I tested it on the swagger on their website and it works fine. Is it possible their api is broken or am I doing something wrong?
This is my current script:
import time
import swagger_client
from swagger_client.rest import ApiException
from pprint import pprint
swagger_client.configuration.api_key['apikey'] = 'API_KEY_HERE'
api_instance = swagger_client.TrackApi()
album_id = '20903197' # str | The musiXmatch album id
format = 'json' # str | output format: json, jsonp, xml. (optional) (default to json)
callback = 'callback_example' # str | jsonp callback (optional)
f_has_lyrics = 'f_has_lyrics_example' # str | When set, filter only contents with lyrics (optional)
page = 3.4 # float | Define the page number for paginated results (optional)
page_size = 3.4 # float | Define the page size for paginated results.Range is 1 to 100. (optional)
try:
api_response = api_instance.album_tracks_get_get(album_id, format=format, callback=callback, f_has_lyrics=f_has_lyrics, page=page, page_size=page_size)
pprint(api_response)
except ApiException as e:
print "Exception when calling TrackApi->album_tracks_get_get: %s\n" % e
and I'm getting this response:

To find the reason this problem need to look at code of swagger-client generated by Swagger Editor: for a sync-request look at api_client.py -> __call_api, the result returned from service is deserialized by default that leads to an empty payload.
To fix it need to disable deserialization by set the param _preload_content=False.
Reproducing steps:
Take swagger.json of MusixMatch-service on github
Use Swagger Editor to generate python-client based on swagger.json
Install the autogenerated module swagger-client
Run code
import swagger_client
from swagger_client.rest import ApiException
import json
configuration = swagger_client.Configuration()
configuration.api_key['apikey'] = '..'
api_instance = swagger_client.TrackApi(swagger_client.ApiClient(configuration))
album_id = 20903197
try:
api_response = api_instance.album_tracks_get_get(album_id, _preload_content=False)
result = json.loads(api_response.data)
print(result)
except ApiException as e:
print("Exception when calling TrackApi->album_tracks_get_get: %s\n" % e)
