I need to upload this code

#include <Wire.h>
#include <SparkFun_RV8803.h> // Get the library here: http://librarymanager/All#SparkFun_RV-8803

RV8803 rtc;

void setup()
{
  Wire.begin(17, 16); // Start I2C on SDA = GPIO17, SCL = GPIO16

  Serial.begin(115200);
  Serial.println("Read Time from RTC Example");

  if (rtc.begin() == false)
  {
    Serial.println("Something went wrong, check wiring");
    while (1);
  }
  Serial.println("RTC online!");
}

void loop()
{
  if (rtc.updateTime() == true) // Updates the time variables from RTC
  {
    String currentDate = rtc.stringDate(); // Get the current date in dd/mm/yyyy format
    currentDate.replace("/", "-"); // Replace '/' with '-'
    String currentTime = rtc.stringTime(); // Get the time
    Serial.print(currentDate); // Print the date
    Serial.print(" "); // Print a space
    Serial.println(currentTime); // Print the time
  }
  else
  {
    Serial.print("RTC read failed"); // Error message if time update fails
  }
  delay(1000); // Wait for 1 second before updating again
}

But WHILE UPLOADING, I am getting this
