Reactive Gateway + Microservice MVC + OAuth2

[pascalgrimaud]

Overview of the issue

Currently, a Reactive Gateway can't communicate with a Microservice MVC, if we use OAuth2.
It works well with JWT.

Motivation for or Use Case

Our Microservices stack should work.

Reproduce the error

• generate a Microservice MVC, with Entities
• generate a Reactive Gateway with Entities
• start all
• try to access to the microservice

Or you can use this JDL:

application {
 config {
   baseName store
   applicationType gateway
   packageName io.github.pascalgrimaud.store
   serviceDiscoveryType eureka
   authenticationType oauth2
   prodDatabaseType postgresql
   cacheProvider hazelcast
   buildTool maven
   clientFramework angularX
   testFrameworks [cypress]
   reactive true
 }
 entities *
}

application {
 config {
   baseName crm
   applicationType microservice
   packageName io.github.pascalgrimaud.crm
   serviceDiscoveryType eureka
   authenticationType oauth2
   prodDatabaseType mysql
   buildTool maven
   serverPort 8081
   reactive false
 }
 entities *
}

entity Product {
   name String required
   description String
   price BigDecimal required min(0)
   size Size required
   image ImageBlob
}
enum Size {
   S, M, L, XL, XXL
}
entity Customer {
   firstName String required
   lastName String required
   gender Gender required
   email String required pattern(/[a-z0-9._+-]{1,20}@[a-z0-9]{3,15}\.[a-z]{2,4}/)
   phone String required
   addressLine1 String required
   addressLine2 String
   city String required
   country String required
}
enum Gender {
   MALE, FEMALE, OTHER
}
entity ProductOrder {
   placedDate Instant required
   status OrderStatus required
   code String required
   invoiceId String
}
enum OrderStatus {
   COMPLETED, PENDING, CANCELLED
}
entity OrderItem {
   quantity Integer required min(0)
   totalPrice BigDecimal required min(0)
   status OrderItemStatus required
}
enum OrderItemStatus {
   AVAILABLE, OUT_OF_STOCK, BACK_ORDER
}
relationship ManyToOne {
OrderItem{product(name) required} to Product
}
relationship OneToMany {
  Customer{order} to ProductOrder{customer(email) required},
  ProductOrder{orderItem} to OrderItem{order(code) required}
}

service Product, Customer, ProductOrder, OrderItem with serviceClass
paginate Product, Customer, ProductOrder, OrderItem with pagination

/* Entities for Invoice microservice */
entity Invoice {
   code String required
   date Instant required
   details String
   status InvoiceStatus required
   paymentMethod PaymentMethod required
   paymentDate Instant required
   paymentAmount BigDecimal required
}
enum InvoiceStatus {
   PAID, ISSUED, CANCELLED
}
entity Shipment {
   trackingCode String
   date Instant required
   details String
}
enum PaymentMethod {
   CREDIT_CARD, CASH_ON_DELIVERY, PAYPAL
}
relationship OneToMany {
   Invoice{shipment} to Shipment{invoice(code) required}
}
service Invoice, Shipment with serviceClass
paginate Invoice, Shipment with pagination
microservice Customer, Product, ProductOrder, OrderItem, Invoice, Shipment with crm

// will be created under 'docker-compose' folder
deployment {
   deploymentType docker-compose
   appsFolders [store, crm]
   dockerRepositoryName "pascalgrimaud"
   monitoring no
   serviceDiscoveryType eureka
}

I'm adding a bug bounty on this, as it needs time to analyze and fix it.
Maybe try to understand why it works for JWT but not for OAuth2?

[pascalgrimaud]

Here the configuration I tested:

• Reactive Gateway + Microservice Reactive + JWT : 🆗
• Reactive Gateway + Microservice MVC + JWT : 🆗
• Reactive Gateway + Microservice Reactive + OAuth2 : 🆗
• Reactive Gateway + Microservice MVC + OAuth2 : ❌

Increasing the bounty as it needed to be fixed, otherwise, there can't be a new release
