How to add additional properties to model validation at request

[therougeb]

``Hello all,

i'm migrating an application from lb3 and i'm stuck here, I have an endpoint that i want to validate that the request contain an user model instance but i also want it to verify that extra parameters exists (defined on model) i tried several ways to accomplish it but i can't figure how to do the trick.

On the userModel i have:

  // Define well-known properties here
  token?: string
  sku_trial?: string

on the @requestBody parameters i have:

export const userLoginValidation: Partial<RequestBodyObject> = {
  content: {
    'application/json': {
      schema: getModelSchemaRef(User)
    }
  }
}

i have an email validation on the user model email property that works but i can't have it to work when i'm using specific validation without the user Schema Ref

I tried to add additionalProperties with fields to include but it not seems to work

can't figure how to have this behaviour working with lb4

thanks for help
