Cannot manually generate an access token and refresh token

[DerekCrosson]

I am trying to create a token for my users factory to use in rspec tests. This is the factory code:

FactoryBot.define do
  factory :user do
    email { 'user@example.com' }
    password { 'password1234' }

    trait :with_token do
      after(:create) do |user|
        Devise::Api::Token.create!(resource_owner: user)
      end
    end
  end
end

This is the error which is returned:

  1) V1::Organisations API behaves like API Resource GET #index returns a list of resources
     Failure/Error: Devise::Api::Token.create!(resource_owner: user)

     ActiveRecord::RecordInvalid:
       Validation failed: Access token can't be blank, Refresh token can't be blank, Expires in can't be blank, Expires in is not a number
     Shared Example Group: "API Resource" called from ./spec/requests/v1/organisations_spec.rb:8
     # ./spec/factories/users.rb:9:in `block (4 levels) in <main>'
     # ./spec/support/api_resource_shared_examples.rb:15:in `block (2 levels) in <main>'
     # ./spec/support/api_resource_shared_examples.rb:19:in `block (3 levels) in <main>'

I get the same error when trying to generate a token for a user in the rails console like this:

u = User.first

Devise::Api::Token.create!(resource_owner: u)

Am I creating the token incorrectly?

EDIT:

I am now creating the token like this:

create_token_service = Devise::Api::TokensService::Create.new(resource_owner: user, previous_refresh_token: nil)
create_token_service.call

This code successfully creates the token but Devise::Api::Token.where(resource_owner: user).first does not return this newly created token. Instead it returns an old token.

Another edit: Devise::Api::Token.where(resource_owner: user).reload.last loads the new token.
