@Query default parameter with enum | NestJS | Page 1

#

I try to have a default value for an Enum, but it just doesn't work somehow. The funny part is when I change period: Period to period:string it works, but I want to receive a Period not a string

  @Query(
    'period',
    new DefaultValuePipe(Period.WEEKLY),
    new ParseEnumPipe(Period),
  )
  period: Period,
): Promise<Object[]> {
  init(period)
  ....
}

Period is defined as:

  WEEKLY = 'weekly',
  MONTHLY = 'monthly',
  QUARTELY = 'quartely',
}```
