Scheduled lambda with aws-kotlin-jvm-maven not working properly

[mfalcier]

# This is a Bug Report

Description

I've created a Lambda using the following template: aws-kotlin-jvm-maven, printing an hello world inside the handler as a log.
Next i've added

events:
      - schedule: rate(2 minutes)

just under the handler, in functions->hello, in serverless.yml.

Next I've deployed my lambda using serverless deploy.

Looking at logs, i came through something like this:
After first run:
0 [main] INFO com. example.Handler - Hello, World! com.example.Handler@551aa95
After second run:

119497 [main] INFO com. example.Handler - Hello, World! com.example.Handler@551aa95a
119497 [main] INFO com. example.Handler - Hello, World! com.example.Handler@551aa95a

After third run, another log has been added. And after any run, another is added. It looks like it doesn't "destroy" old ScheduledEvents. Same problem occur with the java template.

I've tried a node template, with the same Serverless config, and this is not happening.

I'm using Serverless v 1.24.1

This will reset when the container-instance is re-created.

I resolved this issue by changing the logging dependency to:

<dependency>
    <groupId>io.symphonia</groupId>
    <artifactId>lambda-logging</artifactId>
    <version>1.0.0</version>
</dependency>

I've found a very useful article here: https://blog.symphonia.io/a-love-letter-to-lambda-logging-974b0eb49273

Probably the default logger for that template isn't the best one.
