When I delete a post in my Firebase database I want a cloud function to delete the post's thumbnail in firebase storage accordingly. My issue is when I'm trying to delete the thumbnail I don't think I'm locating the image file correctly.
Here is what I have tried:
const functions = require('firebase-functions')
const admin = require('firebase-admin')
const gcs = require('@google-cloud/storage')()
exports.deletePost = functions.database.ref('Posts/{pushId}').onWrite(event => {
const original = event.data.val()
const previous = event.data.previous.val()
const pushId = event.params.pushId
if (original === null)
return
const filePath = 'Posts/' + pushId + 'thumbnail.jpg'
const bucket = gcs.bucket('postsapp-12312')
const file = bucket.file(filePath)
const pr = file.delete()
return pr
});
This is what I'm getting in logs

For anyone else still head-scratching, I was able to get mine deleted by excluding the bucket name (and hence selecting the default firebase bucket):
const bucket = admin.storage().bucket();
const path = "path/to/file.wav";
return bucket.file(path).delete();
I have managed to fix it. The Issue here was that I was writing my bucket address wrong; it should be something like postsapp-12312.appspot.com instead of postsapp-12312
Update For a better way to put your bucket address check @Robert answer
You can use the firebase functions environment config to get the bucket name:
const bucket = gcs.bucket(functions.config().firebase.storageBucket)
