Upgrading gamelift to AMAZON_LINUX_2023 failed.

Hello,

As conveyed by Jackson , CreateBuild API has request parameters 'OperatingSystem' and 'ServerSdkVersion' to specify the operating system that your game server binaries run on and a server SDK version you used when integrating your game server build with Amazon GameLift.

Please note that, by default Amazon GameLift sets the value of ServerSdkVersion to 4.0.2. Though, the OperatingSystem parameter has no default value. You can't change a build's operating system later.

> CreateBuild - https://docs.aws.amazon.com/gamelift/latest/apireference/API_CreateBuild.html#gamelift-CreateBuild-request-ServerSdkVersion

CreateBuild operation requires build files that are in an Amazon S3 location under an AWS account that you control.

The 'file not found error' you are later receiving can be due to inaccurate S3 object location or no access to the S3 resources for the IAM role attached to GameLift service.

The UploadBuild call creates a new build record in Amazon GameLift and uploads files from a location that you specify.

If you face any issues, please do update it here so that we can help you resolve it.

Hope this helps.

No that's the problem. When i set linux 2023 and sdk 5.1.1 property in create build it gave me " file not found" error instead

Have to use Linux_2 instead, or I can't create builds.

The CreateBuild API has a property for specifying which version of the Amazon GameLift server SDK you are using: https://docs.aws.amazon.com/gamelift/latest/apireference/API_CreateBuild.html#gamelift-CreateBuild-request-ServerSdkVersion

Hope that helps!
