In App Purchase 2 vendor.js error

Good Afternoon,

I’m currently working on trying to integrate In App Purchase 2 (https://ionicframework.com/docs/native/in-app-purchase-2) into my Ionic 3 app and have been running into some major issues. Since I couldn’t get it to work on my app that I’ve already built, I created a fresh app with only one additional page for testing. Try as I might (and I have tried) I cannot get the code to fully run without the following errors in xCode:

2019-06-10 13:19:06.998710-0400 IAP2 Test[7542:1096620] {“line”:76857,“column”:113,“sourceURL”:“ionic://localhost/build/vendor.js”}

2019-06-10 13:19:06.999433-0400 IAP2 Test[7542:1096620] Error Ordering {“line”:76780,“column”:133,“sourceURL”:“ionic://localhost/build/vendor.js”}

Does anyone have any suggestions on what I might try next or what the issue might be? Here are my specs:
