Issue with creating buckets by the AWS S3 SDK

[towerbit]

try
{
  var putBucketRequest = new PutBucketRequest { BucketName = "newBucket" };
  var putResponse = await s3Client.PutBucketAsync(putBucketRequest);
  Console.WriteLine($"Bucket '{bucketName}' created.");
}
catch (AmazonS3Exception ex)
{
    Console.WriteLine($"AWS S3 Error: {ex.Message}");
}

Will recieve AWS S3 Error: Invalid bucket name.
