How to fix “Missing or insufficient permissions at Http2CallStream”

问题

I'm trying to update firestore document from cloud function using nodejs, but getting error

error Logs :

Error: Missing or insufficient permissions.

js/build/src/client.js:101:45)

I tried to change the Cloud Firestore Security Rules, no success

回答1:

The problem was solved this way:

1. Download the secret key from the firebase console.

2. Save the downloaded .json file in the path "./your project path/functions".

3. Add this code to the top of your index.js:

   var serviceAccount = require("./[downloaded file name].json");
   
   admin.initializeApp({
       credential: admin.credential.cert(serviceAccount),
       databaseURL: "https://[your project id].firebaseio.com"
   });
   

4. Deploy the function.
