Expo in app purchase not working, what am I doing wrong?

I’m new to react native, recently coding about in app purchase.

below is my code for handle purchase

const handlePurchase = async (productId) => {
    try {
      setPressedItemId(productId);
      const items = Platform.select({
        ios: [productId],
        android: [productId],
      });
      const { responseCode, results } = await InAppPurchases.getProductsAsync(items);
  
      console.log('Get products response:', responseCode);
      console.log('Products:', results[0].productId);
  
      if (responseCode === InAppPurchases.IAPResponseCode.OK) {
        const { productId } = results[0];
        const purchase = await InAppPurchases.purchaseItemAsync(productId, null, null, true); 
        console.log('Purchase successful');
        console.log('Purchase:', purchase);
        
      } else {
        console.log('Failed to get product information:', responseCode);
        Alert.alert('错误', '无法购买商品', [{ text: '确定' }]);
    
        // 处理购买失败后的逻辑
      }
    } catch (error) {
      console.log('Failed to purchase:', error);
      Alert.alert('错误', '无法购买商品', [{ text: '确定' }]);
      
      // 处理购买失败后的逻辑
    } finally {
      setPressedItemId('');
    }
  };

however

console.log('Purchase successful');
        console.log('Purchase:', purchase);

was not activate after successful purchase.

where am I doing wrong?

I tried looking for different iap option, I still prefer expo in app purchase as it is most simple.
