Multiple libraries were found for ........

I am currently try to upload this code into my NodeMCU ESP8266 with GPS Flight Module. My purpose is to set the NodeMCU to sent longitude and latitude data directly into my firebase to create a real-time tracking device. Currently it shows errors of Multiple libraries were found for (All libraries included). Please help me as i find no answer for this issues.

Multiple libraries are not an error, they are just information so you know which one the compiler used to compile your code.

The error is the missing ArduinoJason.h file which usually means you didn't install it, but need to.

I already add ArduinoJson libraries..

The error that appear is below:

Look at the examples for SoftwareSerial for the ESP8266. You don't specify the Tx and Rx pins in the delcaration, but in the begin() function, along with the baud.

SoftwareSerial ss;

void setup() {
	ss.begin(GPSBaud, RxPin, TxPin);
