Apollo Federation - Hadling the error Entity -> `Entity` is an extension type, but `Entity` is not defined in any service

Question

I wonder if there is any chance to handle the Apollo Federation Error: Apollo Federation - Hadling the error Entity -> Entity is an extension type, but Entity is not defined in any service

The Scenario: In my service "LocalizationService", I extend the Entity "Product" of the "Productservice" like this:

@Directive('@extends')
@Directive('@key(fields: "id")')
export default class Product {
  @Directive('@external')
  @Field(() => ID)
  id!: number
}

What if the service "Productservice" is down ? I got the error:

Product -> `Product` is an extension type, but `Product` is not defined in any service

Is there a way to catch that error or set the entity as nullable in some way??
