Guide for AWS Lambda HTTP yields: io.quarkus.amazon.lambda.runtime.QuarkusStreamHandler ClassNotFoundException in SAM

[bluemonk3y]

Describe the bug
When following the guide:

1. https://quarkus.io/guides/amazon-lambda-http I build the GreetingResource etc.
2. Run > mvn clean install
3. Start SAM using: sam local start-api --template sam.jvm.yaml
4. Navigating the browsers to: http://127.0.0.1:3000/hello
5. Shows class not found on the console:

Fetching lambci/lambda:java8 Docker container image......
Mounting /private/var/folders/2x/mp3q5n8d2136yqf5bl2r571m0000gn/T/tmpt84krkw6 as /var/task:ro,delegated inside runtime container

Expected behavior
Should return the result of the get request to the browser (as shown in the guide)

Actual behavior
browser returns error message:
{"message":"Internal server error"}

To Reproduce
Steps to reproduce the behavior:

1. Follow the guide
2. run SAM
3. point browser to http://127.0.0.1:3000/hello

this looks like an issue with SAM use of DockerMachine permission on sharing/copying files to the container for execution/mounting.

I reproduced it with the SAM HelloWorld app.
https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-getting-started-hello-world.html

You can see it mentioned here:
aws/aws-sam-cli#1092

Temporary workaround:
aws/aws-sam-cli#1254

Or perhaps test this on docker-desktop instead of docker-toolbox (I have no choice because I'm on OSX El Capitan)

I'll see if I can reproduce. I didn't have a problem on my setup on Fedora. Should we just link this in docs?

Reproduced on Windows with stock archetype generated project, found this issue as result.

I have been following "QUARKUS - AMAZON LAMBDA" guide and I got the same error for the native package. I repeated all steps but manually creating the lambda in the AWS console. and I had exactly the same issue when running the code on AWS:

Class not found: io.quarkus.amazon.lambda.runtime.QuarkusStreamHandler: java.lang.ClassNotFoundException
java.lang.ClassNotFoundException: io.quarkus.amazon.lambda.runtime.QuarkusStreamHandler

When I uploaded non-native code (JAR) the lambda worked just fine.

As per the pervious link I believe this is a sam docker issue wrt storage where the class path ends up being broken due to failed mounting or scp. aws/aws-sam-cli#1092

I have been at a conference this week but I will try to take a look when I'm back in the office next week.

I was experiencing this issue for the JVM version (native worked fine!), and I have now updated to the latest version of SAM 0.43, and the problem is resolved - JVM version working and no class not found exception.

[kolorobot]

Quarkus 1.2.1 Final - the native lambda worked - both: Java 8 and Java 11 native build.

I don't use local SAM, I only have GraalVM and I created Lambda manually, uploaded function.zip and it worked.

[bluemonk3y]

I should add, I presume 'native' will work due to a being a different runtime classloader mechanism. It was only on sam-local and seems like an issue with docker-toolkit and not docker desktop.

[oztimpower]

Oops seems the answer on my side was as simple as by default Amazon Lambda only builds a thin jar, which is why it works for native image as it brings in all classes used.

The following property needs to be added (when using maven):
quarkus.package.uber-jar=true

It would be nice if the Amazon Lambda extension by default forced this.

[mszpiler]

I have the same problem like @kolorobot

[oztimpower]

Working fine for me now on 1.4.2

SAM CLI, version 0.52.0
