AWS S3 V3 Error trying to get list of objects inside a bucket. SignatureDoesNotMatch

I have Reactjs project created using create-react-app and a aws s3 bucket in witch I've saved some images that I want to display on my website.
I have created a aws.js where I configure and make the call like this
import { S3Client } from "#aws-sdk/client-s3";
import { ListObjectsV2Command } from "#aws-sdk/client-s3";
const REGION = 'eu-central-1'
const credentials = {
accessKeyId: accessKeyId,
privateKeyId: privateKeyId,
}
const config = {
region: REGION,
credentials: credentials,
}
const bucketName = {
Bucket: bucketName,
}
const s3Client = new S3Client(config);
export const run = async () => {
try{
const command = new ListObjectsV2Command(bucketName);
const data = await s3Client.send(command);
console.log("SUCCESS\n", data);
}
catch(err) {
console.log("ERROR\n", err);
}
}
I have also created a .env filder where I saved the keys with and without REACT_APP prefix but the result is the same. Invalidating the credentials.
For credentials I've checked and rechecked 10 times and I also created a new user and use those keys but nothing. I also configured CORS to allow access from my localhost.
What I'm doing wrong? And is there a complete documentation from A-Z on what to use AWS services? Including v3, api doc, credentials set up and everything.
P.S. It's my first time using AWS so some docs would be much apreciated. Thanks in advance
UPDATE---
I tried to use aws javascript sdk v2 and now it works. Here is the code that I used to list objects inside a bucket
But it works only when I used AWS.config.update if I passed the configuration to the bucket it still thrown an error
const AWS = require('aws-sdk');
AWS.config.update({
region: region,
accessKeyId: accessKeyId,
secretAccessKey: secretAccessKey
});
let s3 = new AWS.S3()
export const testFnc = () =>{
s3.listObjects({
Bucket: 'artgalleryszili.digital'
}, (res, err) => {
if(err){
console.log(err);
}
else{
console.log(res);
}
})
}

how to retrieve image from firebase storage and display it on a webpage using google-cloud and node js

i store my image on firebase storage now i wanted to display it on my page
const firebase = require('./../config/firebase');
const gcloud = require('google-cloud');
const fs = require('fs');
var storage = gcloud.storage({
projectId: 'test-a1e76',
keyFilename: 'test-a1e76-firebase-adminsdk-7111d-124guy123eac.json',
});
var bucket = storage.bucket('test-a1e76.appspot.com');
this is how my set up looks like.
and this is my get method.
router.get('/image', function (req,res) {
var remoteReadStream = bucket.file('download.png').createReadStream();
var localWriteStream = fs.createWriteStream('/images/watchers/2jIompF9FUZ6A4LnpBcbpHWw8dx2/download.png');
var ss = remoteReadStream.pipe(localWriteStream);
res.send(ss);
})
i only tried this since it was written on the npm docs.of google-cloud works.
i tried putting it inside get method to see how it works.
and after that i got this error..
Error: ENOENT: no such file or directory, open 'C:\images\test\2jIoasd24zd13ase121s2Ww8dx2\download.png'
this is my ajax get method
$.ajax({
url:'/user/image',
type:'GET',
success:function(data){
console.log(data.path);
}
});
can anyone here guide my on how can i retrieve the images from firebase storage and display it on my webpage?. using this google-cloud npm? cause i read some thread that node js doesn't support firebase-storage so they use google-cloud instead.

I got it working this way.
var admin = require("firebase-admin");
...
app.get('/picture', async (req, res) => {
const fileRef = admin.storage().bucket().file('03aead66e97f0d50ce549b6fffc1b6d7.svg');
const hash = await fileRef.download()
res.contentType(fileRef.metadata.contentType);
res.end(hash[0], 'binary');
});

You need only show the image, right? There`s a dirty way to do.
1- Upload one image on your bucket e click on it (in Firebase console).
2- In the right side of screen shows info about your file.
3- Look for "Download Url" (or something like that) and click on it.
4- This is a url example:
https://firebasestorage.googleapis.com/v0/b/coffee-a7e8c.appspot.com/o/coffeeTrue.png?alt=media&token=7f44e575-414d-4d18-8f39-c94a23f6e014
As you can see there is a pattern:
https://firebasestorage.googleapis.com/v0/b/NAME_FILE?alt=media&token=YOUR_TOKEN
Get your token and now you can show all images on your bucket only pass de name of file and your token (like this example).
This works because Firebase provides a Rest API for your services.
Remember: Do auth before or set-up open rules.
Example: Everyone can read. Only auth user can write.
service firebase.storage {
match /b/{bucket}/o {
match /{allPaths=**} {
allow read: if request.auth == null;
allow write: if request.auth != null;
}
}
}

In the firebase function with node I use below code which is working perfectly

admin.auth().setCustomUserClaims "is not a function"

In a Firebase Cloud Function running Express, I am attempting to set custom user claims when a client posts a token to a setCustomClaims route. When I call admin.auth().setCustomUserClaims(uid, {admin: true}) within that route, I get an error saying this is "not a function."
My authentication provider is the email/password provider via Firebase authentication (i.e. I am not creating custom tokens).
Do I have to be creating custom tokens to set custom user claims?
Here is my cloud function code:
const functions = require('firebase-functions');
const admin = require("firebase-admin");
import express from "express"
admin.initializeApp(functions.config().firebase);
const app = express()
app.post('/setCustomClaims', (req, res) => {
uid = "some-uid"
admin.auth().setCustomUserClaims(uid, {admin:true}).then(()=> {
res.end(JSON.stringify( { status: 'success' } ) );
})
});
export let api = functions.https.onRequest((request, response) => {
if (!request.path) {
request.url = `/${request.url}` // prepend '/' to keep query params if any
}
return app(request, response)
})

npm install firebase-admin#latest --save
firebase-admin#5.4.3 work, good luck for fun app.
Note: client needs this code
// Force token refresh. The token claims will contain the additional claims.
firebase.auth().currentUser.getIdToken(true);

In the new SDKs, you no longer instantiate a database references via new Firebase. Instead, you will initialize the SDK via firebase.initializeApp():
BEFORE
var ref = new Firebase("https://databaseName.firebaseio.com");
AFTER
// See https://firebase.google.com/docs/web/setup#project_setup for how to
// auto-generate this config
var config = {
apiKey: "apiKey",
authDomain: "projectId.firebaseapp.com",
databaseURL: "https://databaseName.firebaseio.com"
};
firebase.initializeApp(config);
var rootRef = firebase.database().ref();>
I have found same issue on the stackoverflow, check this: firebase.database is not a function

admin.database is not a function

Iam using firebase admin but when I use exports like
var admin = require('firebase-admin');
var serviceAccount = require('./firebaseconfig.json');
admin.initializeApp({
credential: admin.credential.cert(serviceAccount),
databaseURL: "https://database.firebaseio.com"
});
module.exports = { admin : admin }
and used in another file by require like
var admin = require('../Firebaseconfig/firebase.js');
console.log(admin.database())
then gives error while starting the server
but if iam using admin.database() in the same file then Iam not getting any error.
error snippet:
console.log(admin.database())
TypeError: admin.database is not a function
at Object.

You exported an object containing admin. So you have to use admin.admin.database() :D
Or just export admin. module.exports = admin

Storing Image Using Cloud Functions for Firebase

I'm trying to refactor some code to use Cloud Functions for Firebase. The code should store an image at a path in Firebase storage. For the most part the code is the exact same as before except now instead of
server.post('/', (req, res) => {
// Some code
}
I'm using the following according to the Firebase documentation
exports.getProcessedImage = functions.https.onRequest((req, res) => {
// Some code
});
The code worked previously but now I'm having trouble getting my test image to save to Firebase. Not sure why. I check the Network tab in developer tools and the getProcessedImage endpoint is triggering the code to run and it responds with a 200 code so not sure what the issue is. Thanks in advance for any help!
My full code is below :)
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const request = require('request');
const crypto = require('crypto');
const storage = require('#google-cloud/storage');
// Firebase Project ID and Service Account Key.
const gcs = storage({
projectId: 'snapshelf-aabb55',
keyFilename: './serviceAccountKey.json'
});
const bucket = gcs.bucket('snapshelf-aabb55.appspot.com');
function saveImage(url) {
// Generate a random HEX string using crypto (a native node module).
const randomFileName = crypto.randomBytes(16).toString('hex');
// Fetch image info using a HTTP HEAD request.
// https://developer.mozilla.org/en-US/docs/Web/HTTP/Methods/HEAD
request.head(url, (error, info) => {
if (error) {
return console.error(error);
}
// Download image from Pixelz, then save the image to Firebase
// using the Google Cloud API and the magic of Node Streams.
// https://googlecloudplatform.github.io/google-cloud-node/#/docs/google-
cloud/v0.52.0/storage/file
// http://stackoverflow.com/questions/28355079/how-do-node-js-streams-work
request(url)
.pipe(
bucket.file(`sample/images/${randomFileName}`).createWriteStream({
metadata: {
contentType: info.headers['content-type']
}
})
)
.on('error', (err) => {
// Do something if the upload fails.
console.error(err);
})
.on('finish', () => {
// Do something when everything is done.
// Get download url for stored image
console.log('Image successfully uploaded to Firebase Storage!')
});
});
}
exports.getProcessedImage = functions.https.onRequest((req, res) => {
console.log(req.body.processedImageURL);
/*
if (req.body && req.body.processedImageURL) {
// Get image from Pixelz and save it to Firebase Storage.
saveImage(req.body.processedImageURL);
return res.status(200).end();
}
res.status(400).end();
*/
const url = 'https://www2.chemistry.msu.edu/courses/cem352/SS2017_Wulff/MichiganState.jpg'
console.log(url);
saveImage(url);
console.log('Saving url');
res.status(200).send();
});

Are you deploying your Function on Firebase with Spark Plan (Free)?
If the answer is yes, your problem is because of this:
Firebase projects on the Spark plan can make only outbound requests to Google APIs. Requests to third-party APIs fail with an error. For more information about upgrading your project.
Since you are trying to make an external request, nothing is happening when your Function is executed :(

Thats easy right now! Since you have admin. just change
const bucket = gcs.bucket('snapshelf-aabb55.appspot.com');
to
const bucket = admin.storage().bucket();
