report_winner function doesn't work inside a group stage

[3rdCore]

report_winner function seems not to work correctly while being used for matches inside a group stage. The associated group_player_ids for a player inside a group is not understanted by the function report_winner(..). This function expects a player with the id attribute equals to group_player_ids but get a player with his original id (outsite group stage) and crash.

example, with 2 objects player and match :

In [68]: player
Out[68]: <challonge.participant.Participant at 0x23866bb9c40>

In [69]: player.id
Out[69]: 152547829
In [70]: player.group_player_ids
Out[70]: [17666281] 

In [72]: match.player1_id
Out[72]: 17666281

await match.report_winner(player,score)

Error call : `APIException: ({'errors': ['Winner ID must be one of the player/participant IDs']}, 422, 'Unprocessable Entity', 'tournaments/10145851/matches/247328813', [('match[scores_csv]', '1-0'), ('match[winner_id]', '152547845')])

Thanks for reporting the issue!
I need to test more for group stages it seems...
I'll look into it!

@3rdCore did you create the group stage via API/achallonge?
If so, could you share the code? Thanks!

I created the tournament using the web interface and I then call the tournament using its token.
Every thing was then done using the Challonge API. This is my main function :

  my_user = await challonge.get_user(my_username, my_api_key)
  my_tournament_id = 'ycpl6a79'
  my_tournament = await my_user.get_tournament(my_tournament_id)
  print(my_tournament.name, my_tournament.full_challonge_url)
  #if not (my_tournament.state =='pending'): 
  #    print("tournament reseted")
  #    await my_tournament.reset()
  #print("Beginning of the tournament !")
  await my_tournament.start()
  matches = await my_tournament.get_matches()
  players = await my_tournament.get_participants()
  player_index = {players[i].id:i for i in range(0,len(players))}

  for match in matches:
          player1 = await my_tournament.get_participant(match.player1_id)
          player2 = await my_tournament.get_participant(match.player2_id)
          #print("players id : ", player1.id, " ", player2.id)
          #player1.id = player1.  [0]
          #player2.id = player2.group_player_ids[0]
          #print("players id : ", player1, " ", player2.id)
          winner, score = get_winner_and_score(player1, player2)
          await match.report_winner(winner,score)

ok, so with my_tournament_id = 'ycpl6a79', I'm assuming you set up the (group) tournament on the website and you are then updating the results through the API, right?

[3rdCore]

That's right. I set up the tournament ( number of player, tournament tree.. ) online, does it come from this ?

First of all, the function start() doesn't start the group phase so we have to manually start the group phase on the website ( with the button ) otherwise the tournament is stuck in an in-between phase where the user can't modify anything.

Should I try to totally setup a tournament through the API ?

Have you understand the difference between .id an. .group_player_id ?

Thanks for your help.

[3rdCore]

do you guys figured out what could be the problem ?

[fp12]

No, sorry, I haven't looked into it yet.
And since we can't do groups from the API, it makes testing a bit harder/longer...

[3rdCore]

I've managed to update the scores using the function report_tie(). This function makes it possible to give un-tie scores and therefore undirectly declare a winner (it would appear as a tie on the web interface, but will still rank players in order of their score.)

This is obviously not a solution but could help someone else stuck in the same situation as me.
