Struggling to Integrate AWS GameLift with Unity for Matchmaking and Player Sessions

AWS GameLift Unity C#

I'm following best practices but I'm dealing with I tried several approaches but none seem to work... Recently started working with AWS GameLift to manage multiplayer sessions for my indie game built in Unity. While setting up the matchmaking, I followed the official AWS documentation, but the integration isn't functioning as expected. Specifically, I'm trying to configure the matchmaking configuration to enable players to join sessions seamlessly. Here’s the relevant part of my setup code: ```csharp var matchmakingConfig = new CreateMatchmakingConfigurationRequest { Name = "MyMatchmakingConfig", RuleSetName = "MyRuleSet", RequestTimeoutSeconds = 30, AcceptanceTimeoutSeconds = 30, MinPlayers = 2, MaxPlayers = 10, CustomEventData = "{\"gameType\":\"battleRoyale\"}" }; var response = await gameLiftClient.CreateMatchmakingConfigurationAsync(matchmakingConfig); ``` When I attempt to create the configuration, I keep receiving the following error message from AWS: `400 Bad Request - Invalid Request: Matchmaking configuration does not have valid parameters.` I've double-checked the rule set name and ensured that the players should be able to match, but the error persists. I also attempted to debug by logging the response from the AWS SDK, but it’s not giving much insight beyond the error code. I’ve verified that my IAM roles for accessing GameLift are correctly configured and have permissions for the necessary actions. In addition, I explored different approaches for matchmaking strategies, considering whether the CustomEventData format is causing issues. However, the error remains, even after simplifying it to just basic parameters: ```csharp var simpleConfig = new CreateMatchmakingConfigurationRequest { Name = "SimpleMatchmakingConfig", RuleSetName = "SimpleRuleSet", MinPlayers = 2, MaxPlayers = 2 }; ``` What am I missing in my configuration? Are there specific requirements or limitations for AWS GameLift matchmaking that I might be overlooking? Any insights would be greatly appreciated. My development environment is Windows. Has anyone else encountered this? How would you solve this?
