Получение ошибки builder.knex (...). QueryBuilder не является функцией

Question

При запуске приложения с sails lift все работает нормально и как и ожидалось, но когда я запускаю это в тестовом наборе Jest, оно перестает работать.

В другом StackOverflow вопрос упоминается, что это означает, что конфигурация Knex не была правильно передана в Objection, но нет различий между Knex, использующим Jest, и работающим рабочим кодом.

Функция BeforeAll ()

async function createMockUsers() {
  config.users.forEach(async function(user) {
    await sails.helpers.createUser(
      user.firstName,
      user.lastName,
      user.phone,
      user.password,
      user.role
    );
  });
}

// Before running any tests...
beforeAll(function(done) {
  // process.env = config.env_variables;

  sails.lift({

    // Your sails app's configuration files will be loaded automatically,
    // but you can also specify any other special overrides here for testing purposes.

    // For example, we might want to skip the Grunt hook,
    // and disable all logs except errors and warnings:
    // hooks: { grunt: false },
    log: { level: 'warn' },
    port: 1338,

  }, async function(err) {
    if (err) { return done(err); }
    await createMockUsers();
    // here you can load fixtures, etc.


    return done();
  });
}, 60000);
