Error in mint function when whitelistSettings is set

[edwardysun]

I've been having no problems with Candy Machine configs without whitelistMintSettings, but with the following config, I always get an error (despite having isPresale = false). I was able to successfully mint outside of using Wonka, so I don't think there's something wrong with the config itself.

Candy Machine state:
