Updating from 6.2.0 -> 6.4.2 is a breaking change for us: "Do not define "id". Instead, rely on the database to generate it."

Description

We are modeling tree structures in with UUID primary keys. We specifically chose UUID as type because among other benefits we can generate those IDs in the application and send whole trees to the database in a single transaction without having to go back and forth for each new node we are inserting.

Reproduction Steps

We have this factory:

factory :root_node, class: 'Tree' do
  id { SecureRandom.uuid }
  root_id { id }
end

Expected behavior

The instance should be constructed with identical values for id and root_id (as was the case with FactoryBot 6.2.0). Alternatively we would be fine with overriding this behavior but browsing the Readme or the web for "Do not define "id". Instead, rely on the database to generate it." didn't yield any helpful results.

Actual behavior

Creating instances worked just fine with FactoryBot 6.2.0, but since at latest 6.4.2 this results in the following error:

     FactoryBot::AttributeDefinitionError:
       Attribute generates "id" primary key for Tree"
       Do not define "id". Instead, rely on the database to generate it.

System configuration

factory_bot version: 6.4.2
rails version: 7.0.8
ruby version: 3.2.2

Start with the reported factory definition and compare its behavior between FactoryBot 6.2.0 and 6.4.2 under Rails 7.0.8 and Ruby 3.2.2. Trace the handling of the generated id and the dependent root_id value, then verify that the documented or restored behavior matches the expected UUID values without triggering the AttributeDefinitionError.
