Cloud function storage and deploy target - firebase

Question

I'm using deploy targets on Firebase and everything is working fine except my Cloud functions.
The process.env.FIREBASE_CONFIG env variable doesn't have the right values. The properties "databaseURL" and "storageBucket" are not the one I've configured the target to use
When I use admin.database() it doesn't use the right RTDB I've created and that I want to use
functions.storage.object().onFinalize() doesn't "watch" the right bucket
My .firebaserc file
{
"projects": {
"default": "hatch-rpg",
"dev": "hatch-rpg"
},
"targets": {
"hatch-rpg": {
"hosting": {
"shadra": [
"shadra"
]
},
"database": {
"shadra": [
"hatch-shadra-dev"
]
},
"storage": {
"shadra": [
"hatch-shadra-dev"
]
}
}
}
}
My firebase.json file
{
"firestore": {
"rules": "firestore.rules",
"indexes": "firestore.indexes.json"
},
"database": [
{ "target": "shadra", "rules": "database.rules.json" }
],
"functions": {
"predeploy": [
"npm --prefix \"$RESOURCE_DIR\" run lint",
"npm --prefix \"$RESOURCE_DIR\" run build"
],
"source": "functions"
},
"hosting": [
{
"target": "shadra",
"public": "dist/shadra",
"ignore": [
"firebase.json",
"**/.*",
"**/node_modules/**"
],
"rewrites": [
{
"source": "**",
"destination": "/index.html"
}
]
}
],
"storage": [
{ "target": "shadra", "rules": "storage.rules" }
]
}
I'm initializing Firebase like this
admin.initializeApp(functions.config().firebase);
What am I missing ?
Thanks a lot
EDIT:
I have tried to override FIREBASE_CONFIG by doing firebase functions:config:set firebase.databaseURL="hatch-shadra-dev.firebaseio.com" firebase.storageBucket="hatch-shadra-dev" but it didn't worked because Invalid config name firebase.databaseURL, cannot use upper case. then tried without uppercase and got Cannot set to reserved namespace firebase
How can I override this FIREBASE_CONFIG ? or should I just not use it initialize manually firebase ?

Ok, here's what I did to fix this issue.
Maybe there's a better option or I'm just mis-using Firebase here.
Anyway, heres' the solution:
First, add some config to the project
firebase functions:config:set target.database="hatch-shadra-dev.firebaseio.com" target.bucket="hatch-shadra-dev"
Then use it in the Cloud function with admin.initializeApp()
import * as functions from 'firebase-functions';
import * as admin from 'firebase-admin';
const config = functions.config();
admin.initializeApp({
...config.firebase,
storageBucket: config.target.bucket,
databaseURL: `https://${config.target.database}`
});
