Error compiling for board NodeMCU 1.0 (ESP-12E Module)

[jssahoo]

I am Getting compling error.
Arduino IDE-1.8.12
ESP8266- 2.6.3

Modified Onesignal.h for ESP8266

Sketch:

#define OS_ESP8266

#include <ESP8266WiFiMulti.h>
#include <OneSignal.h>

// Replace with your own OneSignal App ID
#define OS_APP_ID "YOUR_ONESIGNAL_APP_ID_HERE"

// Run your app and put your own player ID here for testing
#define OS_USER_ID "YOUR_ONESIGNAL_USER_ID"

// Your wifi network name
#define WIFI_SSID "example_wifi_network"

// Your wifi network password
#define WIFI_PASSPHRASE "example_wifi_passphrase"

OneSignal onesignal(OS_APP_ID);

ESP8266WiFiMulti wifiMulti;

void setup() {
Serial.begin(115200);

Serial.println("Connecting to wifi");

wifiMulti.addAP(WIFI_SSID, WIFI_PASSPHRASE);

while (wifiMulti.run() != WL_CONNECTED) { //Wait for the WiFI connection completion
delay(500);
Serial.println("Waiting for connection");
}

Serial.println("Connected to " + String(WIFI_SSID));

// Build & send a push notification
OSNotification notif;
notif.contents = "Hello, World!";
notif.headings = "Test Title";
notif.url = "https://www.google.com";

Serial.println("Built notification, building audience");

OSAudience audience(OS_USER_ID);

String result = onesignal.sendNotificationToAudience(notif, audience);

Serial.println("Sent with result:");
Serial.println(result);
}

void loop() {
// No-op
}

Hi @jssahoo, apologies for the slow response! What kind of compiler error are you getting?
