Question [Matchmaker] BadRequest (21400)

When I try to call the "CreateTicketAsync" callback like in this example, I initialize the Unity Services and authenticate myself previously and Multiplay set up. What things I could miss? I set up the matchmaker in the Unity Dashboard. Do I have to do something else before calling "CreateTicketAsync"?

Unity: 2021.3.14f1
Multiplay: 1.0.0-pre.7
Matchmaker: 1.0.0-pre.14

Example Code:

Code (CSharp):

1. private async Task CreateTicket()
2.         {
3.             var attributes = new Dictionary<string, object>();
4.             var players = new List<Player>
5.             {
6.                 new(AuthenticationService.Instance.PlayerId)
7.             };
8.            
9.             // Set options for matchmaking
10.             var options = new CreateTicketOptions("MainWorld", attributes);
11.            
12.             // Create ticket
13.             var ticketResponse = await MatchmakerService.Instance.CreateTicketAsync(players, options);
14.  
15.             // Print the created ticket id
16.             Debug.LogFormat($"Created ticket with id: {ticketResponse.Id}");
17.         }

Thank you for your response.

Yes, luckily I solved the issue. There was 2 different environment one for Production and one for Development. When I looked at the URL while at Multiplayer Dashboard, I realised there were IDs that match this error. Then I deleted Development Environment so there is only one Environment left. And then it worked

But I suggest that this error could be more human-friendly. Maybe the error can indicate explicitly that the problem is actually about a different environment setup

 

Well that's not a proper solution. How can one change the environment the ticket is being created towards? I also have two environments where development is the only one properly setup. How can I tell MatchmakerService to create a ticket in that environment to avoid the error?

Code (CSharp):

1. var options = new InitializationOptions();
2. options.SetEnvironmentName("dev");
3.  
4. await UnityServices.InitializeAsync(options);

This will help defining an environment beforehand. That's what it fixed for me proplery
