AWS lambda extension fails to Deserialize trigger Classes correctly

[StefanVanDyck]

Describe the bug
When running my DynamoDB-stream triggered lambda I receive the following error:
2021-01-21 01:37:10,665 ERROR [io.qua.ama.lam.run.AbstractLambdaPollLoop] (Lambda Thread) Failed to run lambda: com.fasterxml.jackson.databind.exc.MismatchedInputException: Cannot deserialize instance of java.util.Date out of VALUE_NUMBER_FLOAT token at [Source: (sun.net.www.protocol.http.HttpURLConnection$HttpInputStream); line: 1, column: 196] (through reference chain: com.amazonaws.services.lambda.runtime.events.DynamodbEvent["Records"]->java.util.ArrayList[0]->com.amazonaws.services.lambda.runtime.events.DynamodbEvent$DynamodbStreamRecord["dynamodb"]->com.amazonaws.services.lambda.runtime.events.models.dynamodb.StreamRecord["ApproximateCreationDateTime"]) ... at io.quarkus.amazon.lambda.runtime.AbstractLambdaPollLoop$1.run(AbstractLambdaPollLoop.java:78)

This happens because AWS passes unix timestamps as a float value with milliseconds after the decimal point.

My handleRequest method looks like this:
public LambdaResponse handleRequest(com.amazonaws.services.lambda.runtime.events.DynamodbEvent trigger, Context context)

I am using a native build(GraalVM), not sure if that matters.

Expected behavior
I expect the lambda to be trigger using a Strongly-Type Java Object as event.

Actual behavior
The lambda Crashes with a jackson Deserialization error.

To Reproduce

Will provide reproducer.

Steps to reproduce the behavior:

1. Create a simple quarkus lambda project with a DynamoDB event in the handler method
2. Deploy using dynamodb-stream trigger
3. Put an item in the dynamodb table

Environment (please complete the following information):

• AWS lambda

Forgot to mention the work around was to add a custom Date Deserializer to quarkus.
This was easily achieved using an ObjectMapperCustomizer and copying the logic from com.amazonaws.services.lambda.runtime.serialization.events.modules.DateModule.

It just seems like this should work out-of-the-box when using the aws lambda extension.

[patriot1burke]

You are not using the quarkus dynamo extension correct? I agree this should work out of the box. We're having a bit of problem with deserializing AWS event types. They all seem to follow a different pattern. Some of the classes don't have setter methods, and it looks like others like dynamo do different date serialization.

Indeed, I am not using the dynamo extension.
I included a small reproducer starting from the lambda maven archetype with no additions.

It has 2 "integration" tests that mimick the behaviour on AWS.

[hartimcwildfly]

Still present in latest Quarkus version (3.19.2)

Problem still present in Quarkus version 3.23.3

[geoand]

@mickado82 any chance you can add an up to date reproducer?

Thanks

@geoand I manged to reproduce and solve my issue using StefanVanDyck package posted on Jan 22, 2021.
I can upload a new version with Quarkus version updated to 3.23.3
