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.

[NellyWhads]

@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.

[proppy]

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

[afnalin]

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.

[NellyWhads]

@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

[istudiomobile]

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

[lanhnguyen2010]

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.

[harshgar]

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!

[Jackfr0zt]

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

[harshgar]

@Jackfr0zt Yes I solved it. I used IDE version "1.6.9" plus I removed the older version of the firebase library and re-downloaded and re-installed it that solved my issue. There was an issue with the push function of that library that was resolved in the later version of the library so u need to download the latest version of firebase master library.

[baudcode]

@lanhnguyen2010 the returned object is empty because FIREBASE_JSONBUFFER_SIZE in FirebaseObject.h is set too low. Replace the line
#define FIREBASE_JSONBUFFER_SIZE JSON_OBJECT_SIZE(32)
with e.g.
#define FIREBASE_JSONBUFFER_SIZE JSON_OBJECT_SIZE(128)

[lenguyenvu007]

@baudcode : it should be considered more when you increase to JSON_OBJECT_SIZE(128)
The ESP8266 might become wdt,
because over memory at: StaticJsonBuffer<FIREBASE_JSONBUFFER_SIZE> buffer_;

Inside library file: FirebaseObject.h
Please check it and confirm again!

[proppy]

Sorry for the late reply, you should be able to define JSON_OBJECT_SIZE in your own sketch.

Filed #349 to track improving error reporting.

@proppy - in Arduino IDE, anything you define in sketch does not get propagated into library code. So defining it won't work unless you modify header of the library itself. We can, however, modify library to have JSON memory size setting.

FirebaseObject.h is set too low. Replace the line

[kotl]

@proppy it does not redefine it in the library:
The Arduino IDE compiles libraries individually so you would need to pass the define as a -D option during the compile. The Arduino IDE does not currently provide a facility for you to easily do that. Arduino 1.5 provides some functionality via the boards.txt system but this probably will not provide the flexibility you need.

Quoted from https://stackoverflow.com/questions/14418936/overriding-define-in-libraries

[proppy]

@kotl I think it might work in ArduinoJson case, since it's an header only library.
Maybe we could turn FirebaseArduino into a header library to do the same?

#353 could help as we could remove most of the code and only keep FirebaseArduino.h

[rishini]

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!

[falery]

@rishini same with me, I don't can connecting my firebase to esp..

[preksha02]

same issue! i use esp8266MOD ,everything is perfectly, but nothing is shown on firebase. Please Help!

[Chriton]

@rishini @falery @preksha02 try this https://github.com/Chriton/Firebase-Arduino/tree/master/Arduino%20Project see the Troubleshooting section

[rishini]

Thanks, @Chriton but that's also not working. Do you know any different ways to solve this problem?

[Chriton]

@rishini don't know any other, that worked for me

[rishini]

Please tell me @Chriton when I am adding the zip files that you mentioned do I have to remove any libraries?

[Chriton]

@rishini just follow the steps in https://github.com/Chriton/Firebase-Arduino/tree/master/Arduino%20Project#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.

[rishini]

Thank you very much @Chriton you saved my project.
It's about the fingerprint. The latest fingerprint is "E2 34 53 7A 1E D9 7D B8 C5 02 36 0D B2 77 9E 5E 0F 32 71 17" Make sure to put this" ; "after the fingerprint. And remove the key also.
Guys, @preksha02 @falery try that. It may be work for you also.
Thanks.

[preksha02]

@rishini the latest fingerprint that you have send is also not working.

@preksha02 Make sure to close the whole Arduino IDE after adding the new fingerprint. Then open it and try the code.

[preksha02]

Yah i did this. Actually i was using v2 version , then it was fine working with this and now i am working on v3 version of esp board so it creates problem.
