Arduino uno + esp8266 as wifi with 2 sensor code failed to send data to Channel

I have this code at the bottom and it always shows me a message that read data failed, what is the problem? "Tinker CAD simulator"

// Tinkercad Arduino Tutorials: To Interface ESP8266+ThingSpeak+Arduino in Tinkercad Simulator

String ssid = "Simulator Wifi"; // SSID to connect to WIFI

String password = "Our virtual wifi has no password"; //

String host = "https://api.thingspeak.com";

const int httpPort = 80;

String uri = "/update?api_key=Q63ZZ2IFAYQ6I6HV";

String field1 = "field1";

String field2 = "field2";

int setupESP8266(void){

// Start our ESP8266 Serial Communication

Serial.begin(115200); // Serial connection over USB to computer

Serial.println("AT"); // Serial connection on Tx / Rx port to ESP8266

delay(10); // Wait a little for the ESP to respond

if (!Serial.find("OK")) return 1;

Serial.println("AT+CWJAP=\"" + ssid + "\",\"" + password + "\"");

delay(10); // Wait a little for the ESP to respond

if (!Serial.find("OK")) return 2;

// Open TCP connection to the host:

Serial.println("AT+CIPSTART=\"TCP\",\"" + host + "\"," + httpPort);

delay(50); // Wait a little for the ESP to respond

if (!Serial.find("OK")) return 3;

return 0;

}

void sensors(void){

int tempSensor1 = map(analogRead(A0),20,350,-40,125);

int gasSensor2 = map(analogRead(A1),10,350,0,100);

// Construct our HTTP call

String httpPacket= "GET "+ uri +"&"+field1 +"="+ String(tempSensor1)+"&"+ field2 +"="+String(gasSensor2)+ " HTTP/1.1\r\nHost: " + host + "\r\n\r\n";

int length = httpPacket.length();

Serial.println("tempSensorvalue: "+ String(tempSensor1)+"\n\n");

Serial.println("gasSensorvalue: "+ String(gasSensor2)+"\n\n");

Serial.print("AT+CIPSEND=");

Serial.println(length);

delay(10); // Wait a little for the ESP to respond if (!Serial.find(">")) return -1;

// Send our http request

Serial.print(httpPacket);

delay(10); // Wait a little for the ESP to respond

if (!Serial.find("SEND OK\r\n")) return;

}

void setup() {

setupESP8266();

}

void loop() {

sensors();

delay(10000);

}
