The file sandboxReceipt couldn't be opened because there is no such file

Hi,

I am working on In-App Purchase using StoreKit 2 and getting an error The file sandboxReceipt couldn't be opened because there is no such file when user does a first time purchase auto-renewal subscription. The second purchase, (using a different product ID for a 2nd time auto renew subscription)) does not return an error and correctly returns the second purchase receipt. Here are the sample codes and following example from https://developer.apple.com/documentation/storekit/in-app_purchase/implementing_a_store_in_your_app_using_the_storekit_api :

func purchasing(_ product: Product) async {
  do {
    if try await purchase(product) != nil {
      if try await getReceipt() {
        print("purchase successful")
      } else {
        print("purchase failed")
      }
    } else {
      print("purchase failed")
    }
  } catch {
    print("error", error.localizedDescription)
  }
}

func purchase(_ product: Product) async throws -> Transaction? {
  do {
    // Begin a purchase
    let result = try await product.purchase()
    switch result {
      case let .success(verification):

        let transaction = try checkVerified(verification)

        // Deliver content to the user.
        await updatePurchasedIdentifiers(transaction)

        // Always finish a transaction.
        await transaction.finish()

        return transaction

      case .userCancelled, .pending:
        return nil
      default:
        return nil
    }
  } catch {
    return nil
  }
}

func checkVerified<T>(_ result: VerificationResult<T>) throws -> T {
  // Check if the transaction passes StoreKit verification.
  switch result {
    case .unverified:
      // StoreKit has parsed the JWS but failed verification. Don't deliver content to the user.
      throw StoreError.failedVerification
    case let .verified(safe):
      // If the transaction is verified, unwrap and return it.
      return safe
  }
}

@MainActor
func updatePurchasedIdentifiers(_ transaction: Transaction) async {
  if transaction.revocationDate == nil {
    // If the App Store has not revoked the transaction, add it to the list of `purchasedIdentifiers`.
    purchasedIdentifiers.insert(transaction.productID)
  } else {
    // If the App Store has revoked this transaction, remove it from the list of `purchasedIdentifiers`.
    purchasedIdentifiers.remove(transaction.productID)
  }
}

// Send to third party payment provider
func getReceipt() async throws -> Bool {
  // Get the receipt if it's available
  if let appStoreReceiptURL = Bundle.main.appStoreReceiptURL {
    do {
      let receiptData = try Data(contentsOf: appStoreReceiptURL, options: .alwaysMapped)
      print(receiptData)
      let receiptString = receiptData.base64EncodedString(options: [])
      print("receiptString:", receiptString)
      return true
    }
    catch {
      /// The file `sandboxReceipt` couldn't be opened because there is no such file
      print("Couldn't read receipt data with error: " + error.localizedDescription)
      return false
    }
  } else {
    return false
  }
}
