Solution

 

DynamoDB Local을 특정 region이 없으나 아래와 같이 DynamoDBClient생성시 region값을 설정해야함.

 

어떤값을 넣어도 상관없음

 

    @Bean
    public DynamoDbAsyncClient dynamoDbAsyncClient() {
        return DynamoDbAsyncClient.builder()
                .region(Region.of(region))
                .endpointOverride(URI.create(dynamoDBEndpoint))
                .credentialsProvider(StaticCredentialsProvider.create(
                        AwsBasicCredentials.create(accessKey, secretKey)))
                .build();
    }
