Firebase Json data : error message

exit status 1

'class FirebaseData' has no member named 'jsonData'

I encountered this when compiling the code on Arduino IDE. How do I resolve this error?

what code?

Which version of the Firebase library are you using - do its own examples compile correctly.

Maybe search the verbose compiler output for mention of the Firebase library to see which version is actually being picked up - sometimes there is confusion if you have multiple versions installed.

The following are my declaration and libraries:

#include <ESP8266WiFi.h>
#include <FirebaseESP8266.h>
#include <Adafruit_AMG88xx.h>
#define WIFI_SSID "iaspl"
#define WIFI_PASSWORD "password59"

FirebaseData fbdo;
FirebaseJsonArray arr;
void printResult(FirebaseData &data);
unsigned long sendDataPrevMillis = 0;
Adafruit_AMG88xx amg;

Do I need to uninstall the Firebase library?

for (size_t i = 0; i < arr.size(); i++)
{
Serial.print(i);
Serial.print(", Value: ");

        ***FirebaseJsonData &jsonData = data.jsonData();***
        //Get the result data from FirebaseJsonArray object
        arr.get(jsonData, i);
        if (jsonData.typeNum == FirebaseJson::JSON_BOOL)
            Serial.println(jsonData.boolValue ? "true" : "false");
        else if (jsonData.typeNum == FirebaseJson::JSON_INT)
            Serial.println(jsonData.intValue);
        else if (jsonData.typeNum == FirebaseJson::JSON_FLOAT)
            Serial.println(jsonData.floatValue);
        else if (jsonData.typeNum == FirebaseJson::JSON_DOUBLE)
            printf("%.9lf\n", jsonData.doubleValue);
        else if (jsonData.typeNum == FirebaseJson::JSON_STRING ||
                 jsonData.typeNum == FirebaseJson::JSON_NULL ||
                 jsonData.typeNum == FirebaseJson::JSON_OBJECT ||
                 jsonData.typeNum == FirebaseJson::JSON_ARRAY)
            Serial.println(jsonData.stringValue);
    }

I tried to change to FirebaseJsonData but still having error :cry:

Have you tried compiling the examples that came with the library? That's the first thing to check if you suspect library version confusion.

what do u mean compiling the examples? U mean any examples on Arduino IDE relating to Json?

Usually the library has example code that shows you how to use it.
