Can you share your code snippet?
I guess I've faced something like this, and want to be sure if it related or not on my issue #1020

It looks like you didn't use a promise?
You should use await when calling finishTransaction

@Mitdd9707 Can this be closed? I think you should share some of your code.

I am having the same issue, this is the code I used.

      purchaseUpdateSubscription = RNIap.purchaseUpdatedListener(
        async (purchase) => {
          console.log(purchase);
          const receipt = purchase.transactionReceipt;
          if (receipt) {
            try {
              const ackResult = await RNIap.finishTransaction(purchase);
              console.log('ackResult', ackResult);
            } catch (ackErr) {
              console.warn('ackErr', ackErr);
            }
  
            Alert.alert('purchase error', JSON.stringify(receipt));
          }
        },
      );
