Apps Build And RunTime Error

I have run my project many times before by connecting it to ai 2 companion. Everything was fine and I am using the app installed on my mobile without any problems. But suddenly one day when I open the project and try to run it, a runtime error comes up. I have not made any changes. The previous project is the same. Why is the error still coming? I have opened many other projects besides this one. Many of them are getting the same error. I am sure that there is nothing wrong with my project.

And now if I build the app and install it on my mobile, then after opening the app, a white screen appears and stops.

Are your projects using Firebase and the native Firebase component, which is currently broken ?

Yes, I have almost many projects that use firebase and if firebase cannot be used then my many years of hard work will be in vain. I have been creating multiple projects using firebase for many years and working according to communication with esp32. If everything is in vain, then I will not use MIT app inventor anymore. I may have to use kodular. But I disabled the firebase related logic from my project and tried it but the same problem is how can I believe that this error is due to firebaseDB. When the error occurs, no name of firebase comes. I have used some extensions. Which of these could be the cause of the error? Please tell me by looking at the screenshot.

Firebase can be used, you just need another method

This might be a rash move, you would probably have to re-write all your projects from scratch, and from what i have seen the firebase realtime database implementation on kodular is not the easiest thing to work with.

You would need to completely remove the firebase component from your project to remove the error messages

None of your extensions have recently shown to generate this error.

What can you do?

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

Search through extensions to see if there is a suitable firebase extension that meets your needs

Switch to using CloudDB, AppInventor's own no sql offering

If you feel like doing everything yourself, but still want to work with json nosql, perhaps consider trying infernus

Check every screen for empty sockets, especially on a green 'or' block.

The counters in the lower left of your Blocks Workspace have arrows that can lead you to such errors.

If that doesn't work, export your aia file and upload it here for some one to inspect.

Yes, if I completely remove the firebase component from my project, the problem goes away and everything works properly. Well, will the firebase problem never be fixed? I really need this. There is no other method other than this. Data is updated from my microcontroller to the firebase realtime database and according to that data, the apps do different things, due to which data can be exchanged from different parts of the country. There is no other free way other than this.

Not so...

I did provide you with several options...

Use this extension, it worked 100% for me:
