The agent returned an empty TTS on calling TransactionRequirements constructor

[MFR1]

I am always getting the following error on saying "check transaction with google payment":

"The agent returned an empty TTS"

Can you please let me know what is the issue?

[tocie]

Same here. And it returns "Could not request transactions check with Google payment" in Request

So did you get any solution for this? I think this is happening because of the unsupported countries: https://developers.google.com/actions/transactions/digital/dev-guide-digital

From where are you invoking your skill?

[tocie]

arg.resultType are returning OK when it is transaction_check_action Intent, But returning USER_ACTION_REQUIRED when it using transaction_check_google Intent.

transaction_check_complete Intent requires only 'OK' to process, https://github.com/actions-on-google/dialogflow-transactions-nodejs/blob/418ced27d8ea2c384358069917abcfd8084bd220/functions/index.js#L76

If it is not OK, then the code returns conversation close. This is why conversation is closed.

I'm not sure what kind of action should we or user do to change status "OK". https://developers.google.com/actions/reference/rest/Shared.Types/ResultType

Any updates? It is still returning USER_ACTION_REQUIRED and using Stripe for gateway.

app.intent('transaction_check_google', (conv) => {
  conv.ask(new TransactionRequirements({
    orderOptions: {
      requestDeliveryAddress: false,
    },
    paymentOptions: {
      googleProvidedOptions: {
        prepaidCardDisallowed: false,
        supportedCardNetworks: ['VISA', 'AMEX'],
        // Tokenization with Stripe
        tokenizationParameters: {
          parameters: {
            "gateway": "stripe",
            "stripe:publishableKey": 'pk_test_XXXXXXXXXXXXXXXXXXXXXXXX',
            "stripe:version": "2018-11-08"
          },
          tokenizationType: "PAYMENT_GATEWAY"
        },
      },
    },
  }));
});

app.intent('transaction_check_complete', (conv) => {
  const arg = conv.arguments.get('TRANSACTION_REQUIREMENTS_CHECK_RESULT');
  if (arg && arg.resultType ==='OK') {
    // Normally take the user through cart building flow
      conv.ask(`Looks like you're good to go! ` +
      `Try saying "confirm transaction.".`,
      new Suggestions(['Get Delivery Address', 'confirm transaction']));
  } else {
    conv.close('Transaction failed : ' + arg.resultType );    // Transaction failed : USER_ACTION_REQUIRED
  }
});

Pasted the code. https://gist.github.com/tocie/786fed3172d10822da6709d179ae505e

Make sure you are testing out transactions on a mobile device -- testing transactions via the simulator isn't currently supported.

Hi thanks for answering! I confirmed using phone last time, it was returning as "TRANSACTION_REQUIREMENTS_CHECK_RESULT" but now it returning "OK".

The sample has been significantly updated recently so I recommend going through from the beginning with the latest changes.
