I'm testing in-app-billing API with my app. I've published the app in alpha channel. However, I wasn't able to add any in-app product in Google Play Console. The error says "The in-app product could not be saved. Please check the form for errors." but I don't know where to find the form and the error messages. Here is the screenshot of the error. Anyone can help with this? Thanks!
