I have a flutter app and now i need to accept payments in my app and i want to check if the payment is made by using firebase functions, but i constantly get the error unauthenticated.
I have added app check because that was necessary to implement the payment function i want. I get in appcheck that my request are verified, so i don't think that that is the problem. But if i call the function I get a error [firebase_functions/unauthenticated} UNAUTHENTICATED. I have changed the whole function just to test but I still get the same error:
Index.js
const admin = require("firebase-admin");
admin.initializeApp();
exports.testFunction = functions.https.onCall((data, context) => {
console.log("Auth context:", context.auth);
console.log("App Check token:", context.app);
// Check if the user is authenticated
if (!context.auth) {
console.error("User is not authenticated.");
throw new functions.https.HttpsError(
"failed-precondition",
"The function must be called while authenticated.",
);
}
// Check if App Check is enabled and working
if (!context.app) {
console.error("App Check token is missing or invalid.");
throw new functions.https.HttpsError(
"failed-precondition",
"App Check is not verified or missing.",
);
}
// Return a simple success message
return {message: "Authentication and App Check are working!"};
});
And this is my flutter screen where i test the firebase function:
import 'package:flutter/material.dart';
import 'package:cloud_functions/cloud_functions.dart';
import 'package:firebase_auth/firebase_auth.dart';
class TestFunctionScreen extends StatefulWidget {
@override
_TestFunctionScreenState createState() => _TestFunctionScreenState();
}
class _TestFunctionScreenState extends State<TestFunctionScreen> {
String _result = "Press the button to test Firebase Function";
Future<void> testFunction() async {
try {
// Ensure the user is logged in
User? user = FirebaseAuth.instance.currentUser;
if (user == null) {
setState(() {
_result = "User not logged in. Please log in and try again.";
});
return;
}
print("Authenticated user: ${user.uid}");
// Call Firebase Function
final HttpsCallable callable = FirebaseFunctions.instance.httpsCallable('testFunction');
final response = await callable.call();
setState(() {
_result = "Function Response: ${response.data}";
});
} catch (e, stackTrace) {
print("Error calling function: $e");
print(stackTrace);
setState(() {
_result = "Error: $e";
});
}
}
@override
Widget build(BuildContext context) {
return Scaffold(
appBar: AppBar(
title: Text("Test Firebase Function"),
),
body: Center(
child: Column(
mainAxisAlignment: MainAxisAlignment.center,
children: [
Text(
_result,
textAlign: TextAlign.center,
),
SizedBox(height: 20),
ElevatedButton(
onPressed: testFunction,
child: Text("Test Firebase Function"),
),
],
),
),
);
}
}
This is the log of when I start the app up, until I press the test firebase functions button.

Reset to default 0You either need to enable app-check on the client-side - or disable it on the cloud function side.
Either change:
exports.testFunction = functions.https.onCall((data, context) => {
To:
exports.testFunction = functions.https.onCall({ enforceAppCheck: false }, async (request) => {
Or pass something alike this as second argument of .getHttpsCallable(name, options):
HttpsCallableOptions.Builder().setLimitedUseAppCheckTokens(true).build()
HttpsCallableOptions least exists in Kotlin, unsure about the Dart syntax.

firebase_functions/unauthenticatedis throwing before even reaching your function, so it's the invoker user's permissions missing, not your end user's. Consider that anonCalldeployment from firebase cli tries to set invoke permissions toallUsers, which may fail to be set if your deploying user doesn't have privileges enough, but the function will be deployed anyway. Maybe that's the permission you're missing on the function. You can also go to console.cloud.google/functions/list select the function, then Permissions, and a side panel will show more info and suggestions – maganap Commented Nov 23, 2024 at 13:04
