Getting Bad request(404) when using DynamoDB with SpringBoot

Question

I am new to DynamoDB and I am getting null (Service: AmazonDynamoDBv2; Status Code: 404; Error Code: null; Request ID: null) error when using DynamoDB with spring boot. The server starts up pretty fine but breaks while making DB call. I have DynamoDB setup on local machine. My Gradle files looks like this:

dependencies {
    implementation 'org.springframework.data:spring-data-jpa'
    implementation "org.springframework.data:spring-data-commons:2.0.3.RELEASE"
    implementation 'org.springframework.data:spring-data-releasetrain:1.4.6.RELEASE'
    implementation 'org.springframework.boot:spring-boot-starter-freemarker'
    implementation 'org.springframework.boot:spring-boot-starter-thymeleaf'
    implementation 'org.springframework.boot:spring-boot-starter-web'
    implementation 'com.github.derjust:spring-data-dynamodb:5.1.0'
    implementation group: 'com.amazonaws', name: 'aws-java-sdk-dynamodb', version: '1.11.348'
    compileOnly 'org.projectlombok:lombok'
    annotationProcessor 'org.projectlombok:lombok'
}

I have tried this with 1.11.696 (latest) and with several other versions as well.

I can see there are lots of links explaining similar error with 400 error code but nothing for this. I guess I making some mistake while calling the DB.

Answer 1

So after beating around the bushes, I found out that I was giving the db endpoint as http://localhost:8001 instead of http://localhost:8000 . I was mistaken with the endpoint of a dynamodb-admin which was running on 8001.
