InvalidOperationException: To listen to deferred purchases, please register a listener

Hello, we are getting a lot of reports of this "InvalidOperationException: To listen to deferred purchases, please register a listener via IGooglePlayStoreExtensions" in our unity dash.

Code (CSharp):

1. Google.Play.Billing.GooglePlayStoreImpl.Purchase (UnityEngine.Purchasing.ProductDefinition product, System.String developerPayload) (at <00000000000000000000000000000000>:0)

We have recently implemented the google billing from https://developer.android.com/google/play/billing/unity. I am aware this error is caused by not enabling deferred purchasing onInitialisation, which I am. I am also blocking users from attempting a purchase if the initialisation fails. Any ideas as too how I can handle this? Cheers.

 

Are you using Unity IAP? https://docs.unity3d.com/Manual/UnityIAPGoogleConfiguration.html I'm not familiar with a deferred purchase listener on Google. You might try with the Sample IAP project here https://forum.unity.com/threads/sample-iap-project.529555/
