I decided to take a look at this sample on github and noticed a few things:

I had all the packages except firebase-tools, which is weird because I’ve wrote in command line 70 times npm install -g firebase-tools as the document indicates. So I decided to add it by myself so now package.json contains the firebase-tools dependency

"firebase-admin": "^9.1.1",
"firebase-functions": "^3.11.0",
"firebase-tools": "^8.9.0"

Then I rewrote the require of firebase_tools in index.js:

const firebase_tools = require('firebase-tools')

And just in case I set the token that you get by executing the command line: firebase login:ci

Set here firebase functions:config:set fb.token="SET_TOKEN_HERE"

Now execute the next command line: firebase deploy –only functions to update.

And finally works 🙂

I want to delete a document and all the collections that is inside the document from firestore. For that I’m using cloud function with node 8 as engine and it’s actually deployed. But something isn’t working as expected.

this is my route
/ postsCollection / user / user_posts_collection / large documents

So I want to delete the user document and all the things that contain inside that document => user_posts_collection and its documents

Node.js, Cloud Function

exports.deleteUserPostsDocument = functions
    .runWith({
        timeoutSeconds: 540,
        memory: '2GB'
    })
    .https.onCall(async(data, context) => {

        const path = data.path;

        await firebase_tools.firestore
            .delete(path, {
                project: process.env.GCLOUD_PROJECT,
                recursive: true,
                yes: true,
                token: functions.config().fb.token
            });

        return {
            path: path
        };
    });

Kotlin, call to function

val path = "/posts/user"
val data = hashMapOf("path" to path)

var success = false

functions
    .getHttpsCallable("deleteUserPostsDocument")
    .call(data)
    .continueWith {task ->
        success = task.isSuccessful
    }.await()

return success

The code is exactly the same as they show here, I just removed the code to access if you are just only admin. So there shouldn’t be any problem with that.

I followed all the steps they indicated, with firebase login, firebase login:cli etc.. and I can see the function being deployed into my firebase cloud functions

Question: What am I missing?

Edit 1: Here’s a screenshot that it’s calling to the cloud function, but doesn’t delete anything.
