AWS SDK Java V2 SIGNING_REGION_SCOPE ERROR

Question

I am using next AWS dependency:

<dependency>
  <groupId>software.amazon.awssdk</groupId>
  <artifactId>s3</artifactId>
  <version>2.17.34</version>
</dependency>

And here is my bean configuration for S3Client

@Bean
S3Client amazonS3Client() {
  return S3Client.builder().region(Region.EU_WEST_1).build();
}

And finally here is my implementation method to upload file:

private void uploadToS3(byte[] fileBytes, String fileKey) {
  PutObjectRequest putObjectRequest = PutObjectRequest.builder().bucket("MY_S3_BUCKET_NAME").key(fileKey).build();
  RequestBody requestBody = RequestBody.fromBytes(fileBytes);
  s3Client.putObject(putObjectRequest, requestBody);
}

But this code gives me next error log:

So what is the problem in my configuration so i fix this SIGNING_REGION_SCOPE problem?

Answer 1

Your issue can be related to incorrect POM. Hard to say without seeing all of your project files.

However, refer to the following AWS tutorial that will show you how to successfully use the Amazon S3 Java API V2 in a Spring Boot app. In this example, a S3Client object is created by using a EnvironmentVariableCredentialsProvider:

// Create the S3Client object.
private S3Client getClient() {
    Region region = Region.US_WEST_2;
    S3Client s3 = S3Client.builder()
            .credentialsProvider(EnvironmentVariableCredentialsProvider.create())
            .region(region)
            .build();

    return s3;
}

See:

Creating a dynamic web application that analyzes photos using the AWS SDK for Java

The use case for this example is you create a dynamic web application that analyzes nature images located in an Amazon Simple Storage Service (Amazon S3) bucket by using the Amazon Rekognition service. This app works fine:
