micronaut-function-aws-lambda's Issues

Upgrade micronaut-function-aws-lambda to Micronaut 2.0

Tests do not pass in "complete" projects - NoSuchBeanException in ViesVatValidatorFunctionTest

ViesVatValidatorFunctionTest fails in the "complete" projects with the following error:

example.micronaut.ViesVatValidatorFunctionTest > testViesVatValidatorFunction FAILED
io.micronaut.context.exceptions.NoSuchBeanException at ViesVatValidatorFunctionTest.java:17

It seems that ViesVatValidatorClient from src/test is not registered as a bean to be retrieved in the test via server.getApplicationContext().getBean(ViesVatValidatorClient.class);

example how to use graalvm, cloudwatch event of micronaut lambda

Hi,

I can't find example how to implement AbstractMicronautLambdaRuntime for cloudwatch event.

I try code below
`public class BookLambdaRuntime extends AbstractMicronautLambdaRuntime<CloudWatchLogsEvent, Void, Map<String, Object>, String> {

public static void main(String[] args) {
    try {
        new BookLambdaRuntime().run(args);

    } catch (MalformedURLException e) {
        e.printStackTrace();
    }
}

@Override
@Nullable
protected RequestHandler<Map<String, Object>, String> createRequestHandler(String... args) {
    return new BookRequestHandler();
}

}
`
Run test with cloudwatch event
{
"errorMessage": "Unconvertible input: null"
}

micronaut-function-aws-lambda graalvm native-image build fails

I am unable to build a native application using the micronaut-function-aws-lambda example. However, I am able to create a native application following micronaut-creating-first-graal-app.

Steps to Reproduce

1. git clone https://github.com/micronaut-guides/micronaut-function-aws-lambda.git
2. cd micronaut-function-aws-lambda/complete/vies-vat-validator-graal/
3. sdk use java 19.2.1-grl
4. gu install native-image
5. ./gradlew assemble
6. native-image --no-server --class-path build/libs/vies-vat-validator-0.1-all.jar

When run with native-image --no-server --no-fallback --class-path build/libs/vies-vat-validator-0.1-all.jar fails with:

Error: com.oracle.graal.pointsto.constraints.UnsupportedFeatureException: No instances of org.apache.logging.slf4j.Log4jLogger are allowed in the image heap as this class should be initialized at image runtime. To see how this object got instantiated use -H:+TraceClassInitialization.

Expected Behaviour
Native application should be built

Actual Behaviour
Build Fails

I've tracked it down to the line runtime "com.amazonaws:aws-lambda-java-log4j2:1.0.0" in build.gradle disabling which fixes the build. (upgrading to 1.1.0 didn't help)

Problem With SAM Installation Instructions

The instructions at https://github.com/micronaut-guides/micronaut-function-aws-lambda/blob/master/src/main/docs/guide/sam.adoc contain a link with the text "install SAM" and the link points to https://github.com/awslabs/aws-sam-cli/blob/develop/docs/installation.rst, which is currently 404'ing in the rendered guide at https://guides.micronaut.io/micronaut-function-aws-lambda/guide/index.html.

SAM Local Inovke Fails with ClassNotFoundException: MicronautRequestStreamHandler

I downloaded a fresh copy of the project and tried to run it, but it fails with the following message. Can someone please take a look. Thanks.

UPDATE
Ok that was a naming issue and I fixed it. But now I'm getting this:

aws-lambda example example fails at the sam test

hi I am following the AWS lambda tutorial and when I try to use sam to test it I get

java.lang.Exception: Class io.micronaut.function.aws.MicronautRequestStreamHandler has no public zero-argument constructor Caused by: java.lang.NoSuchMethodException: io.micronaut.function.aws.MicronautRequestStreamHandler.() at java.lang.Class.getConstructor0(Class.java:3082) at java.lang.Class.getConstructor(Class.java:1825)

do I have to create a child implementation of MicronautRequestStreamHandler?

I did create a child and it worked.
