Purchase failed because Purchasing was not initialized correctly

Unity Services
1

I’m testing a consumable purchase on Android and I had it working once but then for an unknown reason it stopped working when I click the buy button.

When checking the ADB LOG it looks like there is a JSON error.

When it worked once I was using manual initialization i.e. not using the provided catalog and buttons.
Now I’m trying the IAP catalog and automatic Initialization but neither approaches are working anymore.

Not really sure what I’m doing wrong.

Please use IAP 1.20.1 and the latest version of Unity. This issue was fixed already. And THANK YOU for providing the logs, it is always very helpful. If you are already using 1.20.1 and a recent version of Unity, we will need to revisit this issue.

I am having a very similar error to summerian and I have checked and everything appears to be updated. I am going to manually update to unity 2018.3 to see if this fixes it.

And make sure you are using IAP 1.20.1 (it’s the latest in the asset store)

I’m already using IAP 1.20.1 and I just upgraded from 2018.3.b12 to Unity 2018.3.0f2 and now I’m getting another error.
I’m now using the codeless approach and created a button via the IAP menu. The product ID corresponds correctly to the Google Play setup.
When I click the button I see this in the log:

@summerian That is a different issue, and may be caused by several things. Make sure you follow the directions here Unity - Manual: Configuring for Google Play Store . And make sure you test with a tester account and not your developer account.

is it possible to test purchase from inside unity ??

No, you need to install on an actual device https://docs.unity3d.com/Manual/UnityIAPGoogleConfiguration.html and https://docs.unity3d.com/Manual/UnityIAPAppleConfiguration.html
