Hi,
take a look at https://aws.amazon.com/blogs/compute/re-platforming-java-applications-using-the-updated-aws-serverless-java-container/.
You can configure and use the SpringDelegatingLambdaContainerHandler implementation or implement your own handler Java class that delegates to AWS Serverless Java Container.
In your case the easiest fix is replacing
handler: com.amazonaws.serverless.proxy.spring.SpringBootLambdaContainerHandler::handleRequest
with
handler: com.amazonaws.serverless.proxy.spring.SpringDelegatingLambdaContainerHandler
in your serverless.yml.
from serverless-java-container.

I think I'm almost there.
I'm getting this message now:
2024-02-22T14:41:01.451 WARN --- [ asgi_gw_0] l.s.apigateway.integration : Lambda output should follow the next JSON format: { "isBase64Encoded": true|false, "statusCode": httpStatusCode, "headers": { "headerName": "headerValue", ... },"body": "..."}
Lambda output: {'errorMessage': 'Could not find class [FluxApplication]', 'errorType': 'java.lang.IllegalArgumentException'}
I've took a look on uploaded jar:
$ jar tf target/frontoffice-0.0.1-SNAPSHOT.jar | grep FluxApplication
me/jeusdi/slab/localstack/flux/presentation/frontoffice/FluxApplication.class
As you can see, FluxApplication in on jar file.
FluxApplication class is:
package me.jeusdi.slab.localstack.flux.presentation.frontoffice;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.FilterType;
import org.springframework.data.mongodb.repository.config.EnableMongoRepositories;

@EnableMongoRepositories(basePackages = "me.jeusdi.slab.localstack.flux.infrastructure")
public class FluxApplication {
public static void main(String[] args) {
SpringApplication.run(FluxApplication.class, args);
}
}In order to set with "main" to pick up for DelegateContainer, I've set MAIN_CLASS environment variable to "FluxApplication" into serverless.yml:
service: espaidoc
provider:
name: aws
runtime: java17
stage: dev
region: us-east-1
versionFunctions: false
package:
artifact: ./target/frontoffice-0.0.1-SNAPSHOT.jar
plugins:
- serverless-localstack
custom:
localstack:
stages:
- dev
host: localstack.localhost
edgePort: 8000
endpointFile: .localstack/endpoints.json
functions:
api:
handler: com.amazonaws.serverless.proxy.spring.SpringDelegatingLambdaContainerHandler
environment:
MAIN_CLASS: FluxApplication
events:
- http:
method: POST
path: /documentsAny ideas?
from serverless-java-container.

Yeah it has to be a fully qualified class name including the package. So in your case:
MAIN_CLASS: me.jeusdi.slab.localstack.flux.presentation.frontoffice.FluxApplication
from serverless-java-container.

Thanks @deki . I was solved it using fully qualified class name.
Another issue here:
I'm getting:
2024-02-22T15:09:13.612 WARN --- [ asgi_gw_3] l.s.apigateway.integration : Lambda output should follow the next JSON format: { "isBase64Encoded": true|false, "statusCode": httpStatusCode, "headers": { "headerName": "headerValue", ... },"body": "..."}

Any suggestion here?
EDIT
I've also tested trying to invoke my function using serverless framework getting the same but more detailed logs. Here the output:
