#23

this would mean that this is undefined

#24

right so then how do i define it i guess i thought i did here

const getRandomRarity = (_rarityOptions) => {
  let randomPercent = Math.random() * 100;
  let percentCount = 0
#25

that seems to be an array, dat doesn’t have data for a particular _rarity

#26

i see hmm im not sure how to fix it ill have to play around i guess

#27

I was stuck in the same error and my solution was to add “?” to avoid undefined error

percentCount += _rarityOptions[i]?.percent;
