Google Assistant : account linking and Actions sdk : fail to see sign in message - actions-on-google

Question

I want to enable account linking on an Google Assistant application using Actions Sdk.
I have already provided the information in the Account Linking section of the AoG Console :
The grant Type is Authorization code.
I use Auth0 as Oauth Server and i checked that the endpoints are functional.
When the application is invoked using the simulator, the server application send the following json response :
{
"expectUserResponse": true,
"finalResponse": null,
"expectedInputs": [{
"possibleIntents": [{
"intent": "actions.intent.SIGN_IN",
"inputValueData": null
}],
"inputPrompt": {
"richInitialPrompt": {
"items": [{
"simpleResponse": {
"textToSpeech": "Merci de vous authentifier",
"ssml": null,
"displayText": "Merci de vous authentifier"
}
}]
}
}
}],
"conversationToken": null,
"isInSandbox": false
}
I expected then to see the message like : it looks like your account … is not linked
Instead of that, the assistant immediately sends the following request to the server :
{
"user": {
"userId": "ABwppHGK6fClByrbLlS8WDM4xfY0qEck5i_kOGMhlJtuj64SjC-8qDqlH3xZ3BN7f9Yz1JDza-sc",
"locale": "fr-CA",
"lastSeen": "2018-04-23T14:12:02Z"
},
"conversation": {"conversationId": "1524493058716", "type": "NEW"},
"inputs": [{
"intent": "actions.intent.SIGN_IN",
"rawInputs": [{"inputType": "KEYBOARD"}],
"arguments": [{
"name": "SIGN_IN",
"extension": {
"#type": "type.googleapis.com/google.actions.v2.SignInValue",
"status": "ERROR"
}
}]
}],
"surface": {
"capabilities": [
{"name": "actions.capability.WEB_BROWSER"},
{"name": "actions.capability.MEDIA_RESPONSE_AUDIO"},
{"name": "actions.capability.SCREEN_OUTPUT"},
{"name": "actions.capability.AUDIO_OUTPUT"}
]
},
"isInSandbox": true,
"availableSurfaces": [
{
"capabilities": [
{"name": "actions.capability.SCREEN_OUTPUT"},
{"name": "actions.capability.AUDIO_OUTPUT"}
]
}
]
}
Did someone have the same problem ? Thanks

Answer 1

I have a working example, but it might be different of what you are doing because I ask the sign-in with dialogflow Integrations' tab for Google Assistant, and not explicitely with the SDK. The code is for the V2 of Dialogflow, I also have one for the V1 but it is now legacy.
This is my BONJOUR intent that is triggered when my app is launched:
const rp = require('request-promise');
app.intent('BONJOUR', (conv) => {
console.log("Debug: SAY_HELLO");
const accessToken = conv.user.access.token;
console.log("Access Token = "+accessToken);
//========Auth with OAuth website========
if (!accessToken) {
conv.ask(new SignIn());
} else {
let options = {
method: 'GET',
url: '[...]',//Oauth URL
headers:{
authorization: 'Bearer ' + accessToken,
}
};
// I use the RP lib as we need Promises for the V2 of Dialogflow.
return rp(options).then((body) => {
let data = JSON.parse(body);
console.log("auth data ="+JSON.stringify(data));
//You can access the auth data easily here
// For example if you want the name, it's in data.given_name, etc...
//Use conv.ask() to say something here
}).catch((error) => {
console.log("Error in auth request"+error);
})
}
});
Update:
This is my JSON mais the SignIn() is called, as I just tested it, it doesn't work (I created an intent that receives the actions_intent_SIGN_IN event from an example. And it never asks for sign In , I'm always in the else.)
Response {
"payload": {
"google": {
"expectUserResponse": true,
"richResponse": {
"items": [
{
"simpleResponse": {
"textToSpeech": "PLACEHOLDER"
}
}
]
},
"userStorage": "{\"data\":{}}",
"systemIntent": {
"intent": "actions.intent.SIGN_IN",
"data": {
"#type": "type.googleapis.com/google.actions.v2.SignInValueSpec"
}
}
}
},
"outputContexts": [
{
"name": [...],
"lifespanCount": 99,
"parameters": {
"data": "{}"
}
}
]
}
Then the request after that is:

I hope it can help you somehow.
