I’m using IAP Button, when testing, if I buy the product everything works fine, but if I cancel, I get an error and I can’t reset the game to its original state before the purchase. As far as I understand, when canceling a purchase, On Purchase Failed should be called, but this does not work and causes an error.

You can only make an actual purchase on a device, not through the fake store in the Editor. On a device, OnPurchaseFailed is indeed called. Also, you’ll want to avoid Codeless IAP, it has not been updated in some time and is missing features.
