Official Hardware Retired Esplora

I wirted this code

#define LED_BUILTIN 22

void setup() {
  // put your setup code here, to run once:
  pinMode(LED_BUILTIN, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:
  digitalWrite(LED_BUILTIN, HIGH);
  delay(1000);
  digitalWrite(LED_BUILTIN, LOW);
  delay(1000);
}

and get a error message:

In file included from sketch\leduj.ino.cpp:1:0:
