title: AWS Java SDK - Unable to find a region via the region provider chain
body: <p>I have gone through the question titled "Setting the AWS region programmatically 1" but it doesn't provide all the answers I need.</p>
  
  <p>Q1: I'm getting a <code>SDKClientException-Unable to find a region via the region provider chain</code>. What am I doing wrong? or is there a typo that I missed.</p>
  
  <pre><code>public class CreateS3Bucket {
  
  public static void main(String[] args) throws IOException {
  
      BasicAWSCredentials creds = new BasicAWSCredentials("aws-access-key", "aws-secret-key");
      AmazonS3 s3Client = AmazonS3ClientBuilder.standard().withCredentials(new AWSStaticCredentialsProvider(creds)).build();
  
      Region region = Region.getRegion(Regions.US_EAST_1);
      s3Client.setRegion(region);
  
      try {
          String bucketName = "testBucket" + UUID.randomUUID();
          s3Client.createBucket(bucketName);
          System.out.println("Bucket Created Successfully.");
  
      } catch(AmazonServiceException awse) {
  
          System.out.println("This means that your request made it AWS S3 but got rejected");
          System.out.println("Error Message:" +awse.getMessage());
          System.out.println("Error Message:" +awse.getErrorCode());
          System.out.println("Error Message:" +awse.getErrorType());
          System.out.println("Error Message:" +awse.getRequestId());
  
      } catch (AmazonClientException ace) {
  
          System.out.println("The Amazon Client encountered an Error with network Connectivity");
          System.out.println("Error Message:" + ace.getMessage());
      }
  
  
  }

  <p>Q2: What code changes needs to be done if I want to build a Lambda Function out of it? I'm aware how to create a lambda function and roles that it needs. Just need to know if the code that I have written needs to changed. How should I implement the LambdaFuctionHandler class as below:</p>
  
  <pre><code>import com.amazonaws.services.lambda.runtime.Context;
  import com.amazonaws.services.lambda.runtime.RequestHandler;
  
   public class LambdaFunctionHandler implements RequestHandler&lt;String, String&gt; {
  
  @Override
  public String handleRequest(String input, Context context) {
      context.getLogger().log("Input: " + input);
  
  
      return null;
  }
  
  }
  </code></pre>
