Firebase.failed()

[NellyWhads]

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

can you recompile with httpclient + ssl debugging on (Tools > Debug Level) and paste the log here?

Thanks in advance.

@proppy - I seem to be having trouble finding the Debug Level settings. This may be a bit of noob question but are you speaking in the context of the Arduino IDE? I am using v1.6.11.

It's in Tools > Debug Level after selecting the ESP8266 module in the board manager.

Hey. I have the same problem. Any operation with the firebase does not work and leads to an empty error. And before the same sketch it worked fine. Were you able to solve this problem?

[comfortme]

@ScorpioNormal same problem. none of the firebase functions works and the error is empty. also couldnt find the debug level.

edit: everything went back to normal after i switch to serial 9600

I have the same problem. But I've more information: when the data at Firebase Database increases, this method ( Firebase.get([path]) ), return .success()==true and the data stored into microcontroller is "undefined". By "undefined" I mean the data is something different from database (in my case I have float values more than zero and I receive zero). When I delete child nodes at [path], the Firebase.get([path]) returns all data correctly. I thing this is some problem related to buffer sizes.
Using the ArduinoJson Assistant (https://bblanchon.github.io/ArduinoJson/assistant/), my data that don't arrive correctly have 799 bytes (size for ESP8266). When I reduce my data to 599 bytes, the data arrive correctly. I have only 2 levels of nested objects (path/level1/level2). I don't know where is the problem, but it seems buffer related and Firebase.success() is true when this problem occours.

@afnalin can you share your MCU and your logging steps? I can try this out on my ESP and see if the buffer size is device specific

Any progress on this? Same problem, sketch isn't talking to Firebase, no error messages. I'm available for tests.

[sindiddle]

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

I get the same problem with @afnalin.

When I try to get FirebaseOject from the root, it returns {} empty Json. I try to specify the path to a child node and it works.

Also check with https://bblanchon.github.io/ArduinoJson/assistant/. The FirebaseObject only works with Json smaller than 772 bytes. I use a NodeMCU 1.0.

For more detail. Below is my data in Firebase database.

Data works (772 bytes). That means I can get FirebaseObject in ESP8266.

{"description":"bxhchc","deviceType":1,"lastConnectedTime":"Tue Aug 01 22:55:40 2017\n","name":"trang1","reset":false,"settings":{"4":{"forceTurnOn":false,"timeSettingsList":[{"days":[0,2,4,7],"end":{"hour":23,"minute":18},"start":{"hour":1,"minute":3}},{"days":[1],"end":{"hour":2}}]}},"uid":"2itLuPyoaXcnrZyd2QkbsxJaAPm1","version":1}

I only add a new child node ("start" :{"hour":2}} ) to make Data become 825 bytes and It went away. Returned FirebaseObject in ESP8266 now is Empty.

{"description":"bxhchc","deviceType":1,"lastConnectedTime":"Tue Aug 01 22:55:40 2017\n","name":"trang1","reset":false,"settings":{"4":{"forceTurnOn":false,"timeSettingsList":[{"days":[0,2,4,7],"end":{"hour":23,"minute":18},"start":{"hour":1,"minute":3}},{"days":[1],"end":{"hour":2}, "start" :{"hour":2}}]}},"uid":"2itLuPyoaXcnrZyd2QkbsxJaAPm1","version":1}

Thanks a lot.

The problem is when you are trying to access to your FirebaseDatabase, you need to:

#define FIREBASE_HOST "yourproject.firebaseio.com/"

You need to write '/' at the end because you are going to access to:

yourproject.firebaseio.comdatabase

Insted of

yourproject.firebaseio.com/database

It is importat to check if you have a '/' while calling the path.

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!

@harshgar did you fix that already? cause we have the same problem.. help me plss
