Unity IAP Button: NullReferenceException: Object reference not set to an instance of an object
So I was using the IAP button as the tutorial showed me and the button won't work ingame only giving me this error:

I know the generic problem with NullReferenceException but I just don't understand this.
Same here, did you find any solution?
Yes. You need to download the sample file too because it has the prefab for it. For some reason the main file 3.0 or something like that doesn't contain the UIFakeStoreCanvas prefab. In the package manager find In App Purchases then check for versions. Update it for the latest if you didn't already then download the sample.
