HttpClientResponseException: Error decoding HTTP response body: Error decoding stream for type S3EventNotification

Question

I am trying to create an AWS Lambda Function using micronaut which will be triggered bt s3 events.

However, when I test the function using console, I am receiving the following error :

    Caused by: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: Cannot construct instance of `com.amazonaws.services.lambda.runtime.events.models.s3.S3EventNotification` (no Creators, like default constructor, exist): cannot deserialize from Object value (no delegate- or property-based Creator)

I uploaded the function code as custom runtime by creating a native image using GraalVM as described in below links

Answer 1

I made a bundle of changes that I saw where different solutions for this issue that were suggested in different blogs:

1. add <maven.compiler.parameters>true</maven.compiler.parameters> to pom as this affects the fasterxml.jackson
2. add

<dependency>
<groupId>com.amazonaws</groupId>
<artifactId>aws-lambda-java-serialization</artifactId>
<version>1.0.0</version>
</dependency>

and use it as:

final PojoSerializer<S3EventNotification> s3EventSerializer =
        LambdaEventSerializers.serializerFor(S3EventNotification.class, ClassLoader.getSystemClassLoader());

S3EventNotification eventNotification = s3EventSerializer.fromJson(message.body());

3. In class use import com.amazonaws.services.s3.event.S3EventNotification;
