I’m using the Yahoo Weather Library

GitHub - delvedor/YahooWeatherProcessing: Yahoo Weather library for Processing
however I get an error whenever i try to create a weather object.
My code:

import processing.serial.*;

Serial dataPort;

String val;

//Settings
boolean use12Time = true;  //24-Hour time or 12-Hour time
int slide = 1;             //Starting slide
int totalSlides = 3;       //# of slides total
int slideTime = 3;         //Time on each slide (s)

//Timer
int savedTime;
int totalTime = slideTime * 1000;

//Yahoo weather
Weather weather = new Weather(23509325, "Celsius");

void setup() {
  size(200, 200);
  dataPort = new Serial(this, "COM5", 9600);
  savedTime = millis();
  while(weather.checkConnection() == false) {
    println("Refresh");
  }
}

void draw() {
  int passedTime = millis() - savedTime;
  if(passedTime > totalTime) {
    slide = (slide + 1) % totalSlides;
    savedTime = millis();
  }
  switch(slide) {
    case 1:
      if(use12Time) {
        if(hour() == 0) {
          dataPort.write("12:" + nf(minute(), 2) + " A" + '\n');
        } else if(1 <= hour() && hour() < 12) {
          dataPort.write(str(hour()) + ':' + nf(minute(), 2) + " A" + '\n');
        } else if(hour() == 12) {
          dataPort.write("12:" + str(minute()) + " P" + '\n');
        } else if(13 <= hour() && hour() < 24) {
          dataPort.write(str(hour() - 12) + ':' + nf(minute(), 2) + " P" + '\n');
        } else if(hour() == 24) {
          dataPort.write(str(hour()) + "12:" +nf(minute(), 2) + " A" + '\n');
        }
      } else {
        dataPort.write(str(hour()) + ':' + str(minute()) + '\n');
      }
    break;
    case 2:
      dataPort.write(str(month()) + '/' + str(day()) + '\n');
    break;
    case 3:
      
    break;
  }
}

The error:
