Access to Firebase with the new version April 25 2026 Version: nb204b-ai2a-2

When I access Firebase in the old version it works, but in the new version this error occurs.

I am having a problem in the version:
Built: April 25 2026 Version: nb204b-ai2a-2
Use Companion: Use Companion: 2.78a or 2.78au

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

However, when I do it in the version:
Compiled: March 26 2026 Version: nb204b
Use Companion: Use Companion 2.78a or 2.78au

Is there a way to fix it or go back to the previous version, I am in class right now and stopped because of this error.

mpanion: 2.78a or 2.78au

Use the Firebase RealtimeDatabase REST api with the AppInventor Web component.
