Failing to Read Nested Data From Firebase Database

Question

I am sending "Appetizers and Snacks" which is in name key from one activity 1 to activity 2.

In activity 2,the data received is simply :

Answer 1

    databaseReference = FirebaseDatabase.getInstance().getReference();
    val ref = database.child("All Categories").child("0").child("recipes")
    
   
    val valueEventListener = object : ValueEventListener {
    override fun onDataChange(dataSnapshot: DataSnapshot) {
         val recipes = dataSnapshot.getValue(Recipes::class.java) // recipes model reading
    }

    override fun onCancelled(databaseError: DatabaseError) {
        
    }
}
ref.addListenerForSingleValueEvent(valueEventListener)
