Hello! My English is poor, I’m using a translator to speak Spanish. I’m having trouble using Firebase. I recently started a project again and the blocks have changed. I’m using a real-time database. My difficulty is that I made all the corresponding changes, assuming they function the same, but I keep getting a NULL error. I’ve already checked the package name, the URL, and the API key, and I’m still getting a NULL error that’s blocking all my progress. As I said, everything works the same as before; I only changed the blocks with the same functions for data requests and responses, and nothing works. I’ve also included the Firebase JSON, and still nothing. I’d like to know if anyone could help me. Thank you very much.

I was facing same issue, now using this extension-
Thank you for considering both options.
use a web component instead, it is much smoother as compared to firebase however web component is asynchronous.
Then, do you really think that Firebase components are synchronous…?
FirebaseDB.GetValue doesn’t wait for a response either → execution still continue for sure and GotValue fires later. Both Firebase and Web components are asynchronous buddy…
Thanks for information, I had initiatlly used firebase db, then I moved to web component. Its been long time since I used the FB DB component.
