[Scripting Question] Help with setting Blank Moves script

[CodenameD]

I was writing a script to generate custom event encounter (where you can spawn any species with any ability, item or move combination). It works when I pass all four moves but I can't get it to work when I want the Pokemon to learn only 1 move (3 should be blank).

The event is triggering this

 pbCustomWildBattle({'species' => :SNORLAX, 'ability' => :PRESSURE, 'level' => 35, 'item' => :AIRBALLOON})

The error

Message: Unknown ID 0.

According to wiki, 0 is supposed to be the ID for no move

The script

species = GameData::Species.get(hash.fetch('species', :BULBASAUR)).id
level = hash.fetch('level', 20)
ability = hash.fetch('ability', :SPEEDBOOST)
item = hash.fetch('item', :LEFTOVERS)
# moves is an array containing a list of moves I want it to spawn with
moves = hash.fetch('moves', [])
genwildpoke = Pokemon.new(species,level)
# Customize the generated pokemon
genwildpoke.ability = ability
genwildpoke.item = item
for i in 0..3
    # if a custom move was not mentioned
    if moves[i].nil?
      # and if this is the first move slot
      if i < 1
        # give this pokemon metronome as the first move [COLOR="Cyan"]THIS WORKS FINE[/COLOR]
        genwildpoke.moves[i] = Pokemon::Move.new(:METRONOME)
      else
        # otherwise give all other slots a "no move" [URL="https://essentialsdocs.fandom.com/wiki/Moves"]as defined here[/URL] [COLOR="Red"]THIS DOES NOT WORK[/COLOR]
        genwildpoke.moves[i] = Pokemon::Move.new(0)
      end
    else 
      # otherwise give it whatever moves i want in that slot [COLOR="Cyan"]THIS WORKS FINE[/COLOR]
      genwildpoke.moves[i] = Pokemon::Move.new(moves[i])
    end
  end
