The admin panel I use to manage a sales team collects leads from multiple sources. One of them is a Facebook campaign for distributing POS terminals, landing in a separate Firebase Realtime Database that until now was only visible through the Firebase Console web UI. The goal: surface those leads directly in the Admin, in a dedicated section for authorized users, sorted by submission date.
Adding a new tab to the existing sidebar dispatcher is a surgical operation — three touch points (tabs array, labels map, else if dispatcher) plus the actual render function. What should've been routine turned into three separate, unrelated bugs, each hiding the next.
Problem one: wrong DB node
The first version of the load function pointed at the database root:
// ❌ Points to root — returns null
