Arduino IoT dashboard "no data received yet"

Good morning,

I'm doing a project with arduino mkr wifi 1010 and mkr iot carrier. The project is a smart garden where I monitor also the temperature, the air humidity and light. However I have a problem with the dashboard. Indeed, until some days ago everything seemed work properly: the dashboard comunicated well with the variables of my project. However now the variables linked seemed are not linked anymore, because the dashboard is stuck to the same values.

I have tried to create a new dashboard and a saw this message on widgets: "No data received yet".

I don't know if there is a problem in my code, anyway I attach the full code here:

#include "thingProperties.h"
#include <Arduino_MKRIoTCarrier.h>
MKRIoTCarrier carrier;

int moistPin = A5;
int dry = 1023;
int wet = 0;
int timer = 3000;

String lightState;
String waterPumpState;

uint32_t lightsOn = carrier.leds.Color(82, 118, 115);
uint32_t lightsOff = carrier.leds.Color(0, 0, 0);

void setup() {
  // Initialize serial and wait for port to open:
  Serial.begin(9600);
  //enable only if you work with the pc
  while (!Serial);
 
  // Defined in thingProperties.h
  initProperties();
 
  // Connect to Arduino IoT Cloud
  ArduinoCloud.begin(ArduinoIoTPreferredConnection);
  //Get Cloud Info/errors , 0 (only errors) up to 4
  setDebugMessageLevel(2);
  ArduinoCloud.printDebugInfo();
 
  //Wait to get cloud connection to init the carrier
  while (ArduinoCloud.connected() != 1) {
    ArduinoCloud.update();
    delay(500);
  }
 
  CARRIER_CASE = true;
  carrier.begin();
  carrier.display.setRotation(0);
  delay(1500);
}

void loop() {
  ArduinoCloud.update();

  //read temperature and humidity
  temperature = carrier.Env.readTemperature();
  humidity = carrier.Env.readHumidity();
  Serial.print("T: ");
  Serial.println(temperature);
  
  //Update touch buttons
  carrier.Buttons.update();
  	
  //function to print out values
  if (carrier.Buttons.onTouchDown(TOUCH0)) {
    printInfo();
  }
  
  if (carrier.Buttons.onTouchDown(TOUCH1)) {
    printInfoRelays();
  }
  
  //read raw moisture value
  int raw_moisture = analogRead(moistPin);

  //map raw moisture to a scale of 0 - 100
  moisture = map(raw_moisture, wet, dry, 100, 0);
  
  //read ambient light
  while (!carrier.Light.colorAvailable()) {
    delay(5);
  }
  int none;
  carrier.Light.readColor(none, none, none, light);
  
  delay(100);
}

void onWaterpumpChange() {
  
  int t=0;
  
  while (waterpump == true && t <= timer){
    carrier.Relay2.open();
    waterPumpState = "PUMP: ON";
    updateScreen();
    //set timer [ms] to turn OFF the pump
    delay(1000);
    t=t+1000;
  }
  waterpump = false;
  carrier.Relay2.close();
  waterPumpState = "PUMP: OFF";
  updateScreen();
  
}

void onArtificialLightChange() {
  if (artificial_light == true) {
    carrier.leds.fill(lightsOn, 0, 5);
    carrier.leds.show();
    lightState = "LIGHTS: ON";
  } else {
    carrier.leds.fill(lightsOff, 0, 5);
    carrier.leds.show();
    lightState = "LIGHTS: OFF";
  }
  updateScreen();
}

//Update displayed Info
void printInfo(){
  carrier.display.fillScreen(ST77XX_BLACK);
  carrier.display.setTextColor(ST77XX_WHITE);
  carrier.display.setTextSize(2);
 
  carrier.display.setCursor(40, 60);
  carrier.display.print("Water: ");
  carrier.display.print(moisture);
  carrier.display.println("%");
  
  carrier.display.setCursor(40, 80);
  carrier.display.print("T: ");
  carrier.display.print(temperature);
  carrier.display.println("C");
  
  carrier.display.setCursor(40, 100);
  carrier.display.print("Hum: ");
  carrier.display.print(humidity);
  carrier.display.println("%");
}

void printInfoRelays(){
  carrier.display.fillScreen(ST77XX_BLACK);
  carrier.display.setTextColor(ST77XX_WHITE);
  
  carrier.display.setTextSize(3);
  carrier.display.setCursor(40, 50);
  carrier.display.print(waterPumpState);
  carrier.display.setCursor(40, 90);
  carrier.display.print(lightState);
}

//Update carrier screen
void updateScreen(){
  printInfoRelays();
}

Thanks in advance for who can help me!

Lorenzo!
