I have upgraded my application from rails 5.2 to 6.1. and Ruby from 2.7 to 3.0 but when i rspec my test cases i got this error when i try to create a factory that have Factory and traits.

FactoryBot.define do
  factory `:registration,` class: "METS::Registration" do
  meeting { create(:meeting) }

  transient do
    attendee_attributes { {} }
  end

  email
  registration_email { email&.value }
  address_postal_code { attendee.business_address&.postal_code }
  attendance_type { METS::Registration.attendance_type_values.sample }
  attendee_type { registration_attendee_type(:invitee) }
  first_name { Faker::Name.first_name }
  last_name { Faker::Name.last_name }
  rsvp_type { meeting.default_attendance_type }

  trait :unfrozen do
    meeting { build :meeting, :unfrozen_for_registrations }
  end

  trait :attended do
    attendance_type { registration_attendance_type(:in_person) }
  end
 end
end

in Rspec/test.rb create(:registration, :unfrozen, :as_employee, attendee: attendee, email: primary_email, email_value: primary_email.value)

Error: Failure/Error: create(:registration, :unfrozen)
