I want to upload my usdz model on s3 bucket. But giving below error while set credential.

let accessKeyId = ProcessInfo.processInfo.environment["AWS_ACCESS_KEY_ID"]
        let secretAccessKey = ProcessInfo.processInfo.environment["AWS_SECRET_ACCESS_KEY"]
        do{
            // Setup AWS credentials, connection config and client
            let credentialsProvider = try StaticCredentialsProvider(Credentials(accessKey: accessKeyId!, secret: secretAccessKey!))
            let configuration = try S3Client.S3ClientConfiguration(region: "sa-east-1", credentialsProvider: credentialsProvider)
            let client = S3Client(config: configuration) 
}
