Error with Firebase component

MIT App Inventor Help

Hi,
I'm trying to create an app with a login and register flow. I followed some tutorials, but I got the following error

Runtime Error:
Attempt to invoke virtual method 'boolean java.lang.String.equals(java.lang.Object)' on a null object reference

At first, I thought it was related to my blocks, so I created a new project with only the Firebase component. I tried to connect with my AI Companion, but I got the same error. These are the configurations that I have for my component, firebase and AI Companion

Firebase component

  • FirebaseToken: Empty
  • FirebaseURL: My firebase URL (https://PROJECT-ID-default-rtdb.firebaseio.com/
  • Use Default: Unchecked
  • Persist: Unchecked
  • ProjectBucket: Empty

Realtime Database

  • Database location: United States (us-central1)
  • Rules: { "rules": { ".read": true, ".write": true } }

MIT AI2 Companion

  • Device: Android
  • Version: 2.77

I have tried everything, but I don't know what else I can do. These are some tutorials I have watched.

Show us your block section.

By the way what was the location you set while creating a project in firebase?

I believe the firebase component is a bit broken at the moment?

If you need to get on with your project, you can use the web component instead:

I don't have any blocks. I just have the components on my screen. My database location is United States (us-central1)

Thank you, I will try that

This worked perfectly. I couldn't set up the storage part, but I could make it work. Thank you so much

Using the web component and the REST api is not a "workaround", just a different approach to using Firebase RTDB and Storage, which also extends far beyond what the Firebase component can do.
