Because you are not logged in to Firebase with an authenticated user. Use the error block to capture this. (assuming you are using the firebase components)

En cuanto apuntas con projectbucket a un nodo de lectura restringida te sale un error de Permission Denied (sin haber pedido leer nada, y sin ni siquiera haber puesto un bloque .DataChanged).
Si no has puesto bloques para capturar errores de FB, entonces al usuario le sale una especie de MessageDialog que dice: FirebaseError Permission denied y tiene que pulsar el botรณn Continue.
Pero basta con poner un bloque When .FirebaseError para capturar el error, y entonces al usuario ya no le molestarรก ningรบn mensaje.

Thank you Martin. This is what I said in the second post in this topic, but perhaps not as eloquently as you :slight_smile:

I have same problem, I dont understand this Chinese language pls can you explain better for me, thanks

In simple terms, if you have firebase rules set to restrict access, then this will generate the permission error. Set your firebase rules to read:true and write:true for the ProjectBucket you have in your app.
