Validations on required fields during deserialization

[Ayush-Kukreti]

Hi community,

I am trying to create a parser for the asyncApi v3.0 version, using the deserializer models provided in the project itself. jackson-models
I am able to deserialize Object using its respective deserializer, the issue is that if there is a required property for an object(eg: in Operations-Object we have action and Channel as required property), then lets say if I have a specification like below, where action property is missing, still the OperationsDeserializer will not throw any error during deserialization. is this expected ?

asyncapi: 3.0.0
info:
  title: Account Service
  version: 1.0.0
channels:
  userSignedup:
    address: user/signedup
operations:
  sendUserSignedup:
    #action: send (commented)
    channel:
      $ref: '#/channels/userSignedup'

Please provide suggestions how I can handle these sort of validations for my asyncapi parser ? or if something I am missing here ?
Thanks in advance.
