BUG

[fervenceslau]

Describe the bug Error when trying to send double data to firebase through a json object: "bad request, Invalid data; couldn't parse JSON object. Are you sending a JSON object with valid key names?".

This happens when I try to send a double value of 0.

Printing the json object I see that the sensor data (double) is being displayed as "0." when this error occurs. Whenever I set some other value to this sensor different than 0, e.g. 0.1, everything works fine...

To Reproduce FirebaseJson json; double doubleVariable = 0;

json.set(pathVariable, doubleVariable);

if (!Firebase.updateNode(gFirebaseData, path, json)) { Serial.println(gFirebaseData.errorReason()); return false; }

IDE and its version:

• Arduino
• 1.8.10

ESP32 Arduino Core SDK version

• 1.0.4

FirebaseESP32 version

• 3.5.9

FirebaseJson version

Thanks for report this.

The bug is in double to string conversion of FirebaseJson library.

I will fix it and update soon.
