firebase deploy only function not recognizing any of my functions

Question

I'm trying to deploy a single cloud function while debugging using the following command:

$ firebase deploy --only functions:trig-users-onUserUpdate

But I get this error:

i  functions: current functions in project: trig-auth-createAuthUser(us-central1), trig-auth-onDeleteUser(us-central1), trig-users-onUserUpdate(us-central1)
⚠  functions: the following filters were specified but do not match any functions in the project: trig-users-onUserUpdate

When I do deploy all functions I see it in the list:

✔  functions[trig-users-onUserUpdate(us-central1)]: Successful update operation. 

I tried adding the (us-central1) but I get this error:

bash: syntax error near unexpected token `('

Any ideas what I am doing wrong?

Answer 1

There seems to be an issue with modules/directories that are imported.

In my case, my index.js was structured like so:

const functions = require('firebase-functions')
const admin = require('firebase-admin')
admin.initializeApp()

const users = require('./triggers/users')
const posts = require('./triggers/posts')
const triggers = {
    users,
    posts
}

exports.trig = triggers

To make it work, replace the - that firebase adds in the name with . and it works so:

// WRONG
$ firebase deploy --only functions:trig-users-onUserUpdate
// RIGHT
$ firebase deploy --only functions:trig.users.onUserUpdate
