SpringBoot – BeanDefinitionOverrideException: Invalid bean definition

I am trying to setup DynamoDB locally with Spring Boot. Initially I got the setup working and was able to write/save to DynamoDB via a repository. From that point I added more classes to build my application. Now when I try to start my application, I get the following exception:

org.springframework.beans.factory.support.BeanDefinitionOverrideException: Invalid bean definition with name 'agentRepository' defined in null: Cannot register bean definition [Root bean: class [org.socialsignin.spring.data.dynamodb.repository.support.DynamoDBRepositoryFactoryBean]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] for bean 'agentRepository': There is already [Root bean: class [org.socialsignin.spring.data.dynamodb.repository.support.DynamoDBRepositoryFactoryBean]; scope=; abstract=false; lazyInit=false; autowireMode=0; dependencyCheck=0; autowireCandidate=true; primary=false; factoryBeanName=null; factoryMethodName=null; initMethodName=null; destroyMethodName=null] bound.

I have searched SO and internet extensively but there were no any useful solution to this. The error message is misleading as well.

My project is of the following hierarchy

ai.test.as
- as
- agent
- business
- intent
- exception
- Agent.java
- AgentDTO.java
- AgentRespository.java
- AgentController.java
- AgentService.java
- AgentServiceImpl.java
- config
- DynamoDBConfig.java

DynamoDBConfig.java

package ai.test.as.config;
import ai.test.as.agent.AgentRepository;
import ai.test.as.agent.intent.template.TemplateRepository;
import com.amazonaws.auth.AWSCredentials;
import com.amazonaws.auth.BasicAWSCredentials;
import com.amazonaws.services.dynamodbv2.AmazonDynamoDB;
import com.amazonaws.services.dynamodbv2.AmazonDynamoDBClient;
import org.socialsignin.spring.data.dynamodb.repository.config.EnableDynamoDBRepositories;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
@Configuration
@EnableDynamoDBRepositories(basePackageClasses = {AgentRepository.class})
public class DynamoDBConfig
{
@Value("${aws.dynamodb.endpoint}")
private String dynamoDBEndpoint;
@Value("${aws.auth.accesskey}")
private String awsAccessKey;
@Value("${aws.auth.secretkey}")
private String awsSecretKey;
@Bean
public AmazonDynamoDB amazonDynamoDB()
{
AmazonDynamoDB dynamoDB = new AmazonDynamoDBClient(getAwsCredentials());
dynamoDB.setEndpoint(dynamoDBEndpoint);
return dynamoDB;
}
@Bean
public AWSCredentials getAwsCredentials()
{
return new BasicAWSCredentials(awsAccessKey, awsSecretKey);
}
}

AgentRepository.java

package ai.test.as.agent;
import ai.test.as.agent.Agent;
import org.socialsignin.spring.data.dynamodb.repository.EnableScan;
import org.springframework.data.repository.CrudRepository;
@EnableScan
public interface AgentRepository extends CrudRepository<Agent, String>
{
}

AgentController.java (Where AgentRepository is used)

@RestController
@RequestMapping(value = "/v1/agents")
public class AgentController
{
@Autowired
private AgentRepository agentRepository;
@RequestMapping(value = "/test", method = RequestMethod.POST)
public void test()
{
Agent agent = new Agent();
agent.setAgentNumber("123456");
agent.setId(1);
agentRepository.save(agent);
}
}

Spring suggests the following:
> The bean 'agentRepository', defined in null, could not be registered. A bean with that name has already been defined in null and overriding is disabled.

What does null mean here? Is it because something wrong in my application config? Also how is it possible that it is already registered?

Please give me some pointers because I so confused about my next steps.
