Problem/Bug Quests event error

The error:

Code:

[11:31:27 ERROR]: §6[Quests] §cLUCK§6 inside §a lightning-strikes: §6inside Event §5return§6 is not a valid potion effect name!
[11:31:27 ERROR]: [Quests] Failed to load Event "return". Skipping.

The events file:

Code:

events:
  DeathFail:
    fail-quest: true
  return:
    message: Látom, sikeresen teljesítetted a küldetést. Ezért jutalmat érdemelsz.
    potion-effect-types:
      - LUCK
      - GLOWING
    potion-effect-durations:

I tried it.
Still the same error.
My events.yml:

Code:

events:
  DeathFail:
    fail-quest: true
  return:
    message: 'Látom, sikeresen teljesítetted a küldetést. Ezért jutalmat érdemelsz.'
    potion-effect-types:
      - LUCK
      - GLOWING
    potion-effect-durations:
      - 1200
      - 40
    potion-effect-amplifiers:
      - 3
      - 1

EDIT: It works without quotes if i remove potion effects, but i need to give potion effects.
