Gamelift credential problem on mobile?

Hi there. We’re working on a Unity GameLift game. It works fine on OSX, windows, and in the editor.

However when making iOS and android builds, we get a credentials error.

Here’s an example stacktrace:

  ConfigurationErrorsException: Type ‘System.Configuration.AppSettingsSection, System.Configuration, Version=, Culture=neutral, PublicKeyToken=<token>’ not found.
at System.Configuration.InternalConfigurationHost.IsDefinitionAllowed (System.String configPath, ConfigurationAllowDefinition allowDefinition, ConfigurationAllowExeDefinition allowExeDefinition) [0x00000] in <filename unknown>:0

at Amazon.AWSConfigs.GetConfig (System.String name) [0x00000] in <filename unknown>:0
at Amazon.AWSConfigs..cctor () [0x00000] in <filename unknown>:0

Here’s our code:

Amazon.AWSConfigs.LoggingConfig.LogResponses = Amazon.ResponseLoggingOption.Always;
Amazon.AWSConfigs.LoggingConfig.LogTo = Amazon.LoggingOptions.Console;
Credentials credentials = new Credentials (); credentials.AccessKeyId = "key";
credentials.SecretAccessKey = "secret";
AmazonGameLiftConfig config = new AmazonGameLiftConfig ();
config.RegionEndpoint = Amazon.RegionEndpoint.USWest2;
_gameLiftClient = new AmazonGameLiftClient (credentials, config);

I am quite baffled here by its ability to work in other environments, but fail hard on mobile. Do we have to use cognito? In Cognito, then, should we just have one user? The user we use just has access to join playersessions.


Hey @JSeligstein - sorry for the troubles. Let me see if I can get some answers on this :slight_smile:

Hey @Amonster_LMBR, no responses here! Any update?

I’m having this issue as well, Unity 2020.1, trying to access Cognito from iOS build. Getting ConfigurationManager giving me a NotSupportedException
