React-native-iap: Buying the same product twice will give an error

Version of react-native-iap

0.3.13

Platforms you faced the error (IOS or Android or both?)

iOS

Expected behavior

Expected to buy a product without an issues

Actual behavior

First time I buy a product_A on a "new" device - it works.
Second time I try to buy the same product_A (no matter if I restart the app or not)
will not work. The error message is: "An unknown or unexpected error has occurred. Please try again later."

Steps to reprodue the behabior

1.Implement IAP as in ReadME. Try to buy an item with this code:

try {
      const msg = await RNIap.prepare()
      const products = await RNIap.getProducts([`${productId}`])
      const purchase = await RNIap.buyProduct(productId)
      this.props.purchaseCoinsPack(coinsPack)
      await RNIap.consumePurchase(purchase.transactionReceipt)
    } catch (err) {
      alert(err.message);
    }

_Just in case I have this code in my componentDidMount() and componentWillUnmount():_

getPurchases = async () => {
    try {
      const purchases = await RNIap.getAvailablePurchases();
      purchases.forEach(async purchase => {
        const boughtPack = R.find(R.propEq('androidStoreId', purchase.productId))(this.props.coinsPacks)
        if (boughtPack) {
          this.props.purchaseCoinsPack(boughtPack);
          await RNIap.consumePurchase(purchase.transactionReceipt);
        }
      })
    } catch (err) {
      console.warn(err); // standardized err.code and err.message available
    } finally {
      this.setState({ isLoading: false })
    }
  }

  async componentDidMount() {
    try {
      await RNIap.prepare()
    } catch (err) {
      console.warn(err);
    }
    this.getPurchases()
  }

  async componentWillUnmount() {
    RNIap.endConnection()
  }

2.First buy works ok. Try to buy same product once again
Get an alert with ""An unknown or unexpected error has occurred. Please try again later."
