firebase-arduino: Firebase.failed()

Hey everyone,

I seem to be having a unique error that I can’t find anyone else facing. When I call Firebase.get("[path]") on a given path in my database, it returns unsuccessfully. As expected, Firebase.failed() is true, however, I can’t see any output with Serial.println(Firebase.error()); (the error is empty). My database url and api key are correct as I can use them in my NodeJS project. My usage is a follows:

After my ESP12E is connected successfully to WiFi, I run Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH); in my setup function. Then, in my loop, I call FirebaseObject temp = Firebase.get("light-options"); (light-options being a path to an object in my database. Yes, I have also tried this with a single value within the object such as "light-options/red".). This is directly followed by: if (Firebase.failed()) { Serial.println("Firebase get failed"); Serial.println(Firebase.error()); } At which point, the console prints the string, but no output for Firebase.error(). Also, I have ensured that the network does remain connected throughout this process.

Any thoughts? I’m not sure how to proceed.

Many thanks, Nelly

any update?still can’t figure it out what’s wrong with my sketch. already tried many tutorials, none of it able to talk to Firebase

[update] solved my problem by erasing the “https://” and “/” (at the end of the sentence) when defining the FIREBASE_HOST

@rishini just follow the steps in https://github.com/Chriton/Firebase-Arduino/tree/master/Arduino Project#troubleshooting :

first check the new Firebase fingerprint here Server Fingerprints. Copy your database address in there (eg. mydatabase.firebaseio.com) and click on Fingerprint Site. For me at this moment it shows: 6F:D0:9A:52:C0:E9:E4:CD:A0:D3:02:A4:B7:A1:92:38:2D:CA:2F:26
Do not just copy this one, maybe it has changed again, so just verify it yourself.
remove the firebase-arduino library added initially like shown in the “Removing an arduino library” section.
download a firebase-arduino zip release from the repository, then extract all the files into a folder of your choice and replace the old fingerprint which can be found in the extracted files -> src/FirebaseHttpClient.h -> kFirebaseFingerprint
after you add the new fingerprint into FirebaseHttpClient.h, save it and put all the files back into a zip file and reimport the library like shown in the “Arduino IDE Setup & adding libraries” section.
restart Arduino IDE and recompile your sketch.

@Chriton - This method really helps me solve the issue…

Hey everyone m having the same issue with my esp. I was using the demo code that comes with esp package to upload data to my firebase and its not able to do so. It’s showing error “setting /number failed:”. So far I have tried everything i could think of I have double checked my secret database key and hostname (tried it with and without that “/” at the end), changed upload speed to 9600 and even tried using older version of ide i.e “1.6.9”. Still no luck. Any help would be appreciated. Thanks!

hey all, It’s urgent plz help. I also have the same problem. I was using the demo code that comes with esp package to upload data to my firebase. It’s showing error “setting /number failed:”. I am using the new arduinojson library. Tried by adding the secrets to FIREBASE_AUTH and also tried by removing it. But none of it didn’t work. If you can help it would be appreciated. Thank you!
