As I am working on QUarkus application I am trying to return Uni but it giving me error:
@GET
@javax.ws.rs.Path("/notification/typeCount")
@Produces({MediaType.APPLICATION_JSON, MediaType.TEXT_PLAIN})
public Uni<Response> getNoti(){
return Uni.createFrom().item(getAllCount()).onItem().transform(f -> f != null ? Response.ok(f) : Response.ok(null))
.onItem().transform(ResponseBuilder::build);
}
public Uni<Object> getAllCount() {
try{
sql="my query";
return client.query(sql).execute().onItem().transform(pgRowSet -> {
Map<String, Object> l = CUtils.mapLogic(pgRowSet);
return l;
});
}
catch(Exception e){
return null;
}
}
But while calling this request from front-end it is giving me below error:
RESTEASY002020: Unhandled asynchronous exception, sending back 500: com.fasterxml.jackson.databind.exc.InvalidDefinitionException: No serializer found for class io.smallrye.mutiny.context.ContextPropagationUniInterceptor$2 and no properties discovered to create BeanSerializer (to avoid exception, disable SerializationFeature.FAIL_ON_EMPTY_BEANS)
Please let me know how to resolve it.
I found one way but I don't think it's proper, if I change below lines:
From:
return Uni.createFrom().item(getAllCount()).onItem().transform(f -> f != null ? Response.ok(f) : Response.ok(null))
.onItem().transform(ResponseBuilder::build);
To:
return Uni.createFrom().item(getAllCount()).onItem().transform(f -> f != null ? Response.ok(f.await().indefinitely()) : Response.ok(null))
.onItem().transform(ResponseBuilder::build);
than it will work. so if I add "f.await().indefinitely()" it works, my question is will it be still reactive?
