Guides on AWS Lambda s3 event fails with micronaut 4.2.2, 4.2.3 : An error occurred during JSON parsing: java.lang.RuntimeException #1410

Using the completed example zip (https://guides.micronaut.io/latest/micronaut-aws-lambda-s3-event-gradle-java.zip) (2024-01-06, micronaut 4.2.2) and following the instructions in https://guides.micronaut.io/latest/micronaut-aws-lambda-s3-event-gradle-java.html to create aws bucket, role, lambda function with appropriate trigger, produced the stack trace (full log in csv attached) :

Just noticed the downloaded zip uses micronaut 4.2.2; will change for 4.2.3 and report back if issue is still there.

marcpa00 commented 8 months ago

Verified with micronaut 4.2.3 : same outcome (but stack trace sightly different)

Result is : 

An error occurred during JSON parsing: java.lang.RuntimeException
java.lang.RuntimeException: An error occurred during JSON parsing

I tried to add SerdeImport annotations as suggested in stack trace to no avail.

@Serdeable
@SerdeImport(S3EventNotification.ResponseElementsEntity.class)
@SerdeImport(S3EventNotification.S3ObjectEntity.class)
public class FunctionRequestHandler
        extends MicronautRequestHandler<S3EventNotification, Void> { // <1>

Stack trace :

Note that trying to use Jackson serialization by adding the jackson-databind dependency does not work either.

Modified dependencies in gradle.build : 

dependencies {
    annotationProcessor("io.micronaut.serde:micronaut-serde-processor")
    annotationProcessor("io.micronaut.validation:micronaut-validation-processor")
    implementation("io.micronaut:micronaut-jackson-databind")
    implementation("com.amazonaws:aws-lambda-java-events")
    implementation("io.micronaut.aws:micronaut-aws-lambda-events-serde")
    implementation("io.micronaut.aws:micronaut-aws-sdk-v2")
    implementation("io.micronaut.aws:micronaut-function-aws")
    implementation("io.micronaut.crac:micronaut-crac")
    implementation("io.micronaut.validation:micronaut-validation")
    implementation("jakarta.validation:jakarta.validation-api")
    implementation("net.coobird:thumbnailator:0.4.17")
    implementation("software.amazon.awssdk:s3:2.17.277")
    runtimeOnly("ch.qos.logback:logback-classic")
    runtimeOnly("org.yaml:snakeyaml")
}
