Malformed response in Actions On Google - dialogflow-es

Question

Was trying to build a transactional Google Assistant App and framed the request Order object as following:
{
"#type": "type.googleapis.com/google.actions.v2.TransactionDecisionValueSpec",
"orderOptions": {
"requestDeliveryAddress": false
},
"paymentOptions": {
"googleProvidedOptions": {
"prepaidCardDisallowed": false,
"supportedCardNetworks": ["VISA", "AMEX", "DISCOVER", "MASTERCARD"],
"tokenizationParameters": {
"tokenizationType": "PAYMENT_GATEWAY",
"parameters": {
"gateway": "stripe",
"stripe:publishableKey": "pk_live_KEY",
"stripe:version": "2019-05-16"
}
}
}
},
"proposedOrder": {
"createTime": "2019-08-11T12:18:36-04:00",
"lastUpdateTime": "2019-08-11T12:18:36-04:00",
"merchantOrderId": "248276353077",
"userVisibleOrderId": "248276353077",
"transactionMerchant": {
"id": "shopifystore.myshopify.com",
"name": "Shoe Store"
},
"contents": {
"lineItems": [{
"name": "Amla Shots",
"id": "29051889385525",
"priceAttributes": {
"type": "REGULAR",
"name": "Item Price",
"amount": {
"currencyCode": "USD",
"amountInMicros": "5000000"
},
"state": "ACTUAL",
"taxIncluded": false
},
"purchase": {
"quantity": "1"
},
"description": ""
}, {
"name": "Amla Shots",
"id": "29051889418293",
"priceAttributes": {
"type": "REGULAR",
"name": "Item Price",
"amount": {
"currencyCode": "USD",
"amountInMicros": "10000000"
},
"state": "ACTUAL",
"taxIncluded": false
},
"purchase": {
"quantity": "1"
},
"description": ""
}]
},
"buyerInfo": {
"email": "123#gmail.com",
"firstName": "123",
"lastName": "123",
"displayName": "123 123"
},
"priceAttributes": [{
"type": "TOTAL",
"name": "Total Price",
"state": "ESTIMATE",
"amount": {
"currencyCode": "USD",
"amountInMicros": "15990000"
},
"taxIncluded": true
}, {
"type": "TAX",
"name": "Tax",
"state": "ESTIMATE",
"amount": {
"currencyCode": "USD",
"amountInMicros": "990000"
},
"taxIncluded": true
}, {
"type": "SUBTOTAL",
"name": "Subtotal",
"state": "ESTIMATE",
"amount": {
"currencyCode": "USD",
"amountInMicros": "15000000"
}
}],
"termsOfServiceUrl": "https://example.com",
"note": "Powered by Example"
}
}
The error message that was showing:
MalformedResponse: Failed to parse Dialogflow response into
AppResponse because of invalid platform response: Tried to parse data
from system intent but failed
Where in the JSON is there a mistake?
