StorageException: An unknown error occurred, please check the HTTP result code and inner exception for server response

Question

I use Firebase Storage to upfile. But it does not work THIS IS MY CODE.

FirebaseStorage storage = FirebaseStorage.getInstance();
StorageReference storageRef = storage.getReferenceFromUrl("gs://the-food-house.appspot.com/");
// Create a reference to "file"
    StorageReference mStorage = storageRef.child("Album Avatar")
            .child(UserUID)
            .child(AvatarUser.getLastPathSegment());
    mStorage.putFile(AvatarUser).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
        @Override
        public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {
            Toast.makeText(SignUpWithEmail.this, "UPLOAD FILE OK", Toast.LENGTH_SHORT).show();
        }
    }).addOnFailureListener(new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            Log.d("ERROR", e.toString());
            Toast.makeText(SignUpWithEmail.this, "Failed", Toast.LENGTH_SHORT).show();
        }
    };

This is rule firebase:

allow read, write: if request.auth != null;

It has given me a headache these past few days. Hope that someone finds the problem. Help me please. Thank you.

Answer 1

This error is generated because of rules defined under rules tab in storage, by deafult the rules will be - rules_version = '2'; service firebase.storage { match /b/{bucket}/o { match /{allPaths=**} { allow read, write if request.auth != null; } } }

if u have not implmented authentication and ttying to store files in storage then implment authentication or just remove it if you are implementing for learning purpose, dont use this in production application.

rules_version = '2'; service firebase.storage { match /b/{bucket}/o { match /{allPaths=**} { allow read, write if true; } } }
