Why do I get this whenever I am trying to get the network interfaces?
com.amazonaws.services.ec2.model.AmazonEC2Exception: null (Service: AmazonEC2; Status Code: 400; Error Code: 400 Bad Request; Request ID: null)

I am using below code for example. This is the only code for testing.
AmazonEC2 amazonEC2 = getEC2Client(); try { DescribeInstancesResult result = amazonEC2.describeInstances(); for(Reservation reservation : result.getReservations()){ System.out.println(reservation.getInstances()); } }catch (AmazonEC2Exception e){ e.printStackTrace(); } protected static AmazonEC2 getEC2Client() { conf = new ClientConfiguration(); conf.setConnectionTimeout(5000); conf.setSocketTimeout(20000); conf.setMaxErrorRetry(2); AmazonEC2 client; if (access_id == null && access_key == null) { client = AmazonEC2ClientBuilder.standard().withClientConfiguration(conf).withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("https://iam.amazonaws.com", "us-east-1")) .withCredentials(new InstanceProfileCredentialsProvider(false)) .build(); } else { client = AmazonEC2ClientBuilder.standard().withClientConfiguration(conf).withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("https://iam.amazonaws.com","us-east-1")) .withCredentials(new AWSStaticCredentialsProvider(new BasicAWSCredentials(access_id, access_key))) .build(); } return client; }
I can access the list of Users in the same class but not the stuff related to Describe*
can anyone please help me in this case ?
