i can’t enter data firebase
I have suddenly the same mistake and I haven’t changed anything
The program has been running for 6 months and everything is fine, and it happened last night, I coded everything well, Firebase is still accessible, is this from the internal application itself?
This is an issue on Firebase, not in the extensions or your app. We had the same problem in Kodular with the native components:
- Root cause: Firebase Database Crash - NullPointerException toLowerCase - #24 by Diego - Bugs - Kodular Community
- Proposed fix: Firebase Database Crash - NullPointerException toLowerCase - #52 by Diego - Bugs - Kodular Community
- Migration guide: Firebase Database Crash - NullPointerException toLowerCase - #59 by Diego - Bugs - Kodular Community
You may want to try different extensions. However, the authentication method of the Token is deprecated and shouldn't be used. In our case, we rebuilt the component using newer libraries and the updated authentication approach...
This error appears to come from the Firebase WebSocket connection layer rather than from the blocks themselves.
A few things to check:
- Verify that the
FirebaseURLis still correct
(new Firebase projects usually use*-default-rtdb.firebaseio.com) - Make sure the Realtime Database is still enabled in Firebase Console
- Check whether Firebase security rules or authentication settings changed recently
- Ensure
UseSSLis enabled if using HTTPS Firebase URLs
The stack trace suggests the WebSocket handshake is receiving an unexpected or missing response header, which can happen if the Firebase endpoint or configuration is invalid.
If possible, please also share:
- the Firebase URL format being used (hide sensitive parts)
- whether this started after changing Firebase settings
- whether it fails on Companion only or also in compiled APK

Same here, I use Firebase to Login in my app.
Have not changed anything, yesterday all was working, today it stopped. Can not Login in my app anymore
Error is showing because there is something changed to Firebase server by firebase.
SOLUTION: use any firebase rtdb extension, here is mine to test with your project: [Paid] Firebase Realtime Database Extension (Everything + Set Rules From Client Side)
This is definatly a Problem with the AI Component for Firebase
