Compilation error for the NodeMCU 1.0 (ESP-12E Module)

Hello everyone, I will create a project about notification via telegram bot. But I can't upload the sketch. Returns an error message.
And other sketches are loaded besides this one .
Telegram sketches:

#include <TelegramCertificate.h>
#include <UniversalTelegramBot.h>

#include <ESP8266WiFi.h>
#include <WiFiClientSecure.h>

const char* ssid = "";
const char* password = "";

#define BOTtoken ""
#define CHAT_ID ""

#define Sensor D0


WiFiClientSecure client;
X509List cert(TELEGRAM_CERTIFICATE_ROOT);
UniversalTelegramBot bot(BOTtoken, client);


void setup() {
  Serial.begin(115200);
  configTime(0, 0, "pool.ntp.org");      // get UTC time via NTP
  client.setTrustAnchors(&cert); // Add root certificate for api.telegram.org
  pinMode(Sensor, INPUT);
  WiFi.mode(WIFI_STA);
  WiFi.begin(ssid, password);
  int a = 0;
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(500);
    a++;
  }

  Serial.println("");
  Serial.println("WiFi connected");
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
  delay(500);
  bot.sendMessage(CHAT_ID, "System started", "");
  delay(1000);

}
void loop() {
  bool value = digitalRead(Sensor);
  Serial.println(value);
  if (value == 1) {
    Serial.println("Motion Detected");
    bot.sendMessage(CHAT_ID, "Motion detected!!", "");
  }
}

try to comment this line

You have a compiler error, not an upload error. Hence your topic has been moved to a more suitable location on the forum.

4

The TelegramCertificate.h file is included by the library, and unfortunately they neglected to put header guards in that file to prevent it being included more than once.

Thanks! I commented on this line. This already gives another error. What should I do next?
This sketch works for the author.

Post the current sketch and the error message - I am not getting any errors here after correcting for the #include.

You wrote that you commented out the line

Did, re-issues this error

Where did you get the UniversalTelegramBot library? TELEGRAM_CERTIFICATE_ROOT is declared in that library, in the file TelegramCertificate.h, so it should not give an error. Did you modify any of the library files???

11

I downloaded it from this author and didn't change anything
I also downloaded the board manager inside arduino

12

Why have you commented out the declaration of cert?
