The program was running fine, a few days ago, but now it just wouldn't read/write to the database. I'm running on ArduinoJson 5.13.5 and using FirebaseArduino library. I have set all the rules to true, would love to know how to debug this error. Also Firebase.error() does not give any output at all!

Apparently the Firebase's fingerprint has changed recently and has caused the above issue!

from here get the latest finger print and change it in the ...\Arduino\libraries\firebase-arduino-master\src\FirebaseHttpClient.h

In the file mentioned above: update the value of static const char kFirebaseFingerprint[] to the new one mentioned above.

P.S. One issue going forward for me(planing on implementing it on a long term basis) is how to be ahead of this issue in the future, so that I can get the data uninterrupted!
