Micronaut: Loggers not appearing in AWS Cloudwatch & Java application not running in local

Question

I have a Micronaut microservice which had to be upgraded with the following version changes:

1. Micronaut bom version: 1.3.1 to 1.3.4
2. Gradle: 5.1.1 to 5.3
3. Graal VM:19.2.1

I am building the native-image using the buildspec.yml as given below:

phases:
  build:
    commands:
      - 'mkdir -p build'
      - 'pwd'
      - 'ls'
      - 'chmod +x build-native-image.sh'
      - './build-native-image.sh'
      - 'cp /usr/lib/graalvm/jre/lib/amd64/libsunec.so libsunec.so'
      - 'chmod 755 bootstrap'
      - 'chmod 755 server'   
      - 'chmod 755 cacerts'   
      - 'chmod 755 libsunec.so'
      - 'BUILD_ID=$(cat build_id.txt)'
      - 'zip -j example-function-$BUILD_ID.zip bootstrap server cacerts libsunec.so build_id.txt'
artifacts:
  files:
     - './example-function-*.zip'

The example-function.zip got deployed to AWS Lambdaand while testing it through APIGateway, I am able to get the response but unable to view the loggers that I used in my service in the CloudWatch Logs.

I have followed this article https://docs.aws.amazon.com/kinesisanalytics/latest/java/cloudwatch-logs-writing.html#cloudwatch-logs-writing-slf4j for adding the Logger dependency to my build.gradle file but the logs are still not showing up on AWS.

Also, I am unable to run the application locally using the command: gradlew run -t classes. The build is successful but the run command does not work as the endpoint in postman says Could not get any response.

I am unsure what the issue is. Any help is greatly appreciated.
