Cannot delete files from firebase collection - node.js

Question

I am following the example listed here, except with modifications due to the API of the new firebase-tools.
exports.clearMessages = functions.runWith({ timeoutSeconds: 540, memory: '2GB' }).https.onCall(messagesController.clearMessages)
export const clearMessages = async (data, context) => {
const uid = context.auth.uid
const path = `users/${uid}/messages`
return firebase_tools.firestore.delete('flightApp3', path, {
recursive: true,
shallow: true,
allCollections: true
}).then(result => {
console.log('delete result', result)
return result
})
}
However, when I run this , I see the following displayed in Cloud Functions log:
Unhandled error { Error

However, I'm pretty sure I have an active project in my firebase CLI.
$ firebase use
Active Project: production (flightApp3)
Project aliases for /Users/myUser/Developer/flightApp3/cloud:
* default (flightApp3)
* production (flightApp3)
Run firebase use --add to define a new project alias.

Answer 1

some options cannot be mixed ...
return firebase_tools.firestore.delete('flightApp3', path, {
// allCollections: true,
recursive: true,
yes: true
}).then(() => {
return {
path: path
};
});
that's how the path is being built up (path and allCollections also do not seem to make sense together): projects/${project}/databases/(default)/documents/users/${uid}/messages
getProjectId.js checks for rc.projects (where options.project is option --project):
module.exports = function(options, allowNull) {
if (!options.project && !allowNull) {
var aliases = _.get(options, "rc.projects", {});
...
these rc.projects are the projects from the .firebaserc file:
{
"projects": {
"default": "flightApp3"
}
}
or run firebase use default to switch from alias production to default (or remove alias production once for a test). FirestoreDelete(project, path, options) also does not care about options.token nor options.project anymore (as the documentation suggests).
$ firebase firestore:delete --help explains the command-line options:
Usage: firestore:delete [options] [path]
Delete data from Cloud Firestore.
Options:
-r, --recursive Recursive. Delete all documents and sub-collections.
Any action which would result in the deletion of child
documents will fail if this argument is not passed.
May not be passed along with --shallow.
--shallow Shallow. Delete only parent documents and ignore documents
in sub-collections. Any action which would orphan documents
will fail if this argument is not passed.
May not be passed along with --recursive.
--all-collections Delete all. Deletes the entire Firestore database,
including all collections and documents.
Any other flags or arguments will be ignored.
-y, --yes No confirmation. Otherwise, a confirmation prompt will appear.
the npm package (the output above) is at version 6.0.1.
just found a relevant comment (but possibly obsolete):
The token must be set in the functions config, and can be generated at the command line by running firebase login:ci.
this hints for environment configuration, so that functions.config().fb.token has the token:
firebase functions:config:set fb.token="THE TOKEN"
one can also obtain the projectId from process.env.FIREBASE_CONFIG.projectId.

Docs https://firebase.google.com/docs/firestore/solutions/delete-collections
In /functions directory install firebase-tools
"firebase-tools": "^7.16.2"
In cloud function import firebase-tools and call delete
const firebaseTools = require("firebase-tools");
...
firebaseTools.firestore.delete(workspaceRef.path, {
project: process.env.GCLOUD_PROJECT, // required
recursive: true, // required
yes: true // required
})
There is no need for a token when calling firebase-tools from a cloud function.
Also the link to the API https://github.com/firebase/firebase-tools/blob/v7.16.2/src/firestore/delete.js with code implementation for FirestoreDelete seems wrong.
I'm successfully calling .delete(path, options) but the code says .delete(project, path, options)?
