problem using quarkus-resteasy-reactive-kotlin-serialization with AwsProxyRequestContext

[Lukpier]

Hi All,

I'm trying to use quarkus-resteasy-reactive-kotlin-serialization on a Kotlin jax-rs reactive endpoint deployed on AWS.
Below the method signature:

  @POST
  @Path("/send")
  fun signUp(request: RegistrationRequest, @Context context: AwsProxyRequestContext): RegistrationResult? =
      service.signUp(request, awsRequestId = request.requestId)

Unfortunately, Quarkus returns Bad request when trying to call this endpoint from APIGateway test page. No error is shown since quarkus itself intercept the request without accessing the method body.

After some trials, I managed to be able to access the context object by using quarkus-resteasy-jackson (so, no kotlin-serialization nor reactive), but this is not what I want to obtain.

Am I missing something?

Thanks for all your work!!

Hi,

Kotlin Serialization only works on types that are annotated with @Serializable.

That said, it might be useful to explore how we can support other types as well.

Hi geoand,

Thanks for your response. I know that; atm, I'm trying to implement a custom serializer for that object (using KSerializer), since it is the only Aws context object i need to access in my application.

Do you think it could work? I will need to switch to Jackson otherwise.

Do you think it could work?

Can't say since I've never tried something like that. @evanchooly might now more

I'd do a bit of experimentation but I think the limitation you're going to run in to is that you need to register and serializers with the SerializersModule used to construct the Json we use. Currently there's no way to configure that as part of quarkus and it seems that's all immutable so it can't be done after the fact.

Understood, so the only solution now is to use jackson (or jsob) for request / context decoding (?)

Yes, Jackson is the only tested way to deserialize input for quarkus-amazon-lambda-rest

Ok, I will use jackson for injecting the entire AwsProxyRequest, then proceeeding as usual with kotlin-serialization.

Hi All,

Just encountered a related problem. I'm trying to use quarkus-amazon-lambda-rest together with quarkus-resteasy-reactive-jackson.

Unfortunately, when trying to call the endpoint described in the main issue description, I receive an automatic BAD_REQUEST from quarkus context. Why does it is happening?

Tried also quarkus-resteasy-jackson and everything goes fine, but I was trying to use resteasy reactive in order to make quarkus-rest-client-kotlin-serialization work as a rest-client.

I noticed that in the maven archetype of quarkus-amazon-lambda-rest there is no trace of quarkus-restasy-reactive, but only quarkus-resteasy. So, can I assume that reactive is not supported with quarkus-amazon-lambda-rest ?

Thanks.

It looks like this is not a Kotlin specific problem. I tried modifying their rest lambda template to use reactive and got the same error. I think reactive might not be supported at the moment for quarkus-amazon-lambda-rest.

@patriot1burke can you have a look at ^ please?

@geoand @patriot1burke hey just wanted to check if there were any updates? thanks!
