Actions on Google: Name Psychic Sample

This sample demonstrates Actions on Google features for use on Google Assistant including permission requests for user information, surface transfer capabilities, user storage, SSML, unrecognized deep link fallbacks, and Google Maps Static API -- using the Node.js client library and deployed on Cloud Functions for Firebase.

Note that if the user is not verified, their information will never be saved across conversations and they will encounter a guest flow (requesting permission) each time.

Enable Billing

Required for running this sample

This sample uses Firebase Cloud Functions to make an HTTP request to Google Maps Static API. If you plan to run the sample, you will need to temporarily upgrade to a Firebase plan that allows for outbound networking, such as the Blaze Plan, also called Pay as you go.

Setup Instructions

Prerequisites

Node.js and NPM
- We recommend installing using NVM
Install the Firebase CLI
- We recommend using version 6.5.0, npm install -g [email protected]
- Run firebase login with your Google account

Configuration

Actions Console

From the Actions on Google Console, New project (this will become your Project ID) > Create project > under More options > Conversational
From the top menu under Develop > Actions (left nav) > Add your first action > BUILD (this will bring you to the Dialogflow console) > Select language and time zone > CREATE.
In the Dialogflow console, go to Settings ⚙ > Export and Import > Restore from zip using the agent.zip in this sample's directory.

Cloud Platform Console

From the Dialogflow console > go to Settings ⚙ and under the General tab > go the Project Id link, which will take you to the Google Cloud Platform console
In the Cloud console, go to Menu ☰ > APIs & Services > Library
Select select Maps Static API > Enable
Under Menu ☰ > APIs & Services > Credentials > Create Credentials > API Key and copy the key.

Firebase Deployment

On your local machine, in the functions directory, run npm install
Run firebase deploy --project {PROJECT_ID}, replace {PROJECT_ID} to deploy the function
Run firebase functions:config:set maps.key={API_KEY} --project {PROJECT_ID}, replace {API_KEY} with the generated API key from earlier and redeploy the function.
- To find your Project ID: In Dialogflow console under Settings ⚙ > General tab > Project ID.
Return to the Dialogflow Console > select Fulfillment > Enable Webhook > Set URL to the Function URL that was returned after the deploy command > SAVE.
```
Function URL (dialogflowFirebaseFulfillment): https://${REGION}-${PROJECT_ID}.cloudfunctions.net/dialogflowFirebaseFulfillment
```
From the left navigation menu, select Integrations > Integration Settings under Google Assistant > Enable Auto-preview changes > Test to open the Actions on Google simulator then say or type Talk to my test app.

Running this Sample

You can test your Action on any Google Assistant-enabled device on which the Assistant is signed into the same account used to create this project. Just say or type, “OK Google, talk to my test app”.
You can also use the Actions on Google Console simulator to test most features and preview on-device behavior.

missing key prop on the config object.

Following the instructions, i was getting this:

Upon inspection, if we change the line 25 of functions/index.js file to this, we get our API key back.
key: config.map.key
After this change, I was able to deploy the firebase function.

Now test simulator is crapped out, but that is across all the Google Action projects. Oh well.

Query pattern missing

@Fleker Why I'm getting this error while publishing app for Production.

Query pattern is missing for custom intent 'handle_permission

multi-user compatible?

Is the intention that this will work for multiple different users on the same device? When my wife and I each just ask GH what our name are, it gets it right. However, when she uses name psychic it gets it wrong. Does the code need to change to support multi-users?

Thanks!

Default welcome Intent

Is it possible to comment out Default welcome Intent in index.js and let Dialogflow handle Welcome Intent. I'm getting an error when I comment out line 154-159 in index.js

Error: Dialogflow IntentHandler not found for intent:

Update readme.md

Please, update the readme.md to reflect the idea of the project and main purpose

Hi @salismt,

Hi Silvano,

I must say first I just started Firebase and Action on Google.

Apparenlty I experience the same issue. But I think I might miss a step while deploying.
Here the steps I took at deployment
In the command window

npm install -g firebase-tools
firebase login
firebase init functions -> Javascript -> all defaults
firebase functions:config:set maps.key=""
firebase deploy --only functions

You mentioned above, " removing data from the associated Firebase DB", however in the firebase console, firebase DB is not in use.....What am I missing?

Thanks

Originally posted by @silvolu in #3 (comment)

Default location?

I only receive Mountain View as my location? I get the location request as expected and the cloud function writes to the Firebase database but always Mountain View. Tested on Android and iOS version of the Google Assistant.

Requesting DEVICE_COARSE_LOCATION does not return location data

When running this sample in the Speaker simulator, conv.device.location is empty when the handle_permission intent is called.

Should we save only the name to the DB?

We currently save the name and the location, but that means the location will always be the first one read, and it can create confusion as seen in #3.
We could re-write the sample to save only the name to the db, and get a fresh location every time it's requested.
