Error 401 when using get_manifests

[Serelue]

I was following the example to try to download the game file using steam.cdn
But an error like this occurs. Is there any way to solve it? 😓

My Code

import gevent.monkey                         
gevent.monkey.patch_all()                    
                                             
from steam.client import SteamClient         
from steam.client import cdn                 
from steam.enums import EResult              
                                             
import getpass                               
import sys                                   

# ( Login Code )

if login_result == EResult.OK:                                 
    if client.logged_on:                                       
        print('OK')                                            
    else:                                                      
        sys.exit(-1)                                           
                                                               
    try:                                                       
        cdn_client = cdn.CDNClient(client)                     
        print(cdn_client.get_manifests(620980))                
    except:                                                    
        pass                                                   
                                                               
    sys.exit(0)

Steam requires a manifest code in order to download content manifests. Either you are not using the latest version of the package, or your account doesn't have license for that app (cant acquire a manifest code).

You can check the version with python -m steam.versions_report

You can read about manifest codes at https://steamdb.info/blog/manifest-request-codes/

I checked the version of the module with the command you gave and version 1.2.1 was installed.
So, I updated the module and tried again.

[<CDNDepotManifest('Beat Saber Content', app_id=620980, depot_id=620981, gid=649695825989344999, creation_time='2022-06-28 13:30:34')>]

Yeap, It's working fine.
