Bug: Jackson Joda time needed for some AWS events

[phipag]

Expected Behaviour

When logging handler events or attempting to extract the correlation ID from an event such as ScheduledEvent, I expect that the event gets serialized to a valid JSON when logging and that the correlation ID extraction is working as expected.

Current Behaviour

For AWS events that use Joda time under the hood, for example ScheduledEvent, we see the following exception:

Joda date/time type `org.joda.time.DateTime` not supported by default: add Module "com.fasterxml.jackson.datatype:jackson-datatype-joda" to enable handling (through reference chain: com.amazonaws.services.lambda.runtime.events.ScheduledEvent["time"]): java.lang.IllegalArgumentException
java.lang.IllegalArgumentException: Joda date/time type `org.joda.time.DateTime` not supported by default: add Module "com.fasterxml.jackson.datatype:jackson-datatype-joda" to enable handling (through reference chain:

The correlation ID is not extracted at all. The event logging falls back to calling toString() on the event. In case of the ScheduledEvent this yields an invalid json due to a non-JSON compliant implementation in the AWS event library.

Example:

{
    "level": "INFO",
    "message": "Handler Event",
    "cold_start": true,
    "thread": "main",
    "function_arn": "arn:aws:lambda:us-east-1:<ACCOUNT_ID>:function:powertools-examples-batch-sq-DemoSQSSenderFunction-kGvQ7guWRsW0",

}

Code snippet

Powertools batch example. SqsBatchSender.java

Possible Solution

We should add Joda time to powertools-serialization.

Steps to Reproduce

Add event logging in SqsBatchSender.java and attempt to extract a correlation ID from the event.
