HTTP PUT method on NodeMCU/ESP8266

Question

I've been trying to send a put request from my esp8266 for a while not but I can't figure out why it doesn't work and there are barely any posts about put requests online I keep getting errors around int httpCode = http.sendRequest("PUT", String(data));

Error log: https://gist.github.com/dkbay/ab3fedf5e89d841d25b24fb829df74ef

#include <ESP8266HTTPClient.h>
#define LED_BUILTIN 2
const char* ssid = "Some SSDI";
const char* password = "Some wifi password"; 
int wifiStatus;
void setup() {
 Serial.begin(115200);\
 pinMode(LED_BUILTIN, OUTPUT);
 delay(200);
 // We start by connecting to a WiFi network
 Serial.println();
 Serial.println();
 Serial.print("Your are connecting to;");
 Serial.println(ssid);
 WiFi.begin(ssid, password);
 while (WiFi.status() != WL_CONNECTED) {
 digitalWrite(LED_BUILTIN, LOW);
 delay(500);
 digitalWrite(LED_BUILTIN, HIGH);
 Serial.print(".");
 }
} 
void loop() {
 wifiStatus = WiFi.status();
 if(wifiStatus == WL_CONNECTED){
 HTTPClient http;
 http.begin("http://google.com/");
 http.addHeader("Content-Type", "application/json");
 String data = "{\"on\":false}";
 int httpCode = http.sendRequest("PUT", String(data));
 String payload = http.getString();
 Serial.println(httpCode);
 Serial.println(payload);
 http.end();
 Serial.println("");
 Serial.println("Your ESP is connected!");
 Serial.println("Your IP address is: ");
 Serial.println(WiFi.localIP()); 
 }
 else{
 Serial.println("");
 Serial.println("WiFi not connected");
 }
 delay(1000); // check for connection every once a second
}

• Juraj: what should it do and what does it? Shouldn't 'false' in json be in ""?
• Dkbay: @Juraj It wasn't in quotes when I made it in node... It should send a "PUT" request to my hue lights to update them but instead it htrows this error gist.github.com/dkbay/ab3fedf5e89d841d25b24fb829df74ef
• Juraj: it doesn't compile, not "doesn't work". use sendRequest("PUT", data.c_str());

HTTPClient http;
http.begin("http://google.com?on=false");
http.addHeader("Content-Type", "application/json");
int httpCode = http.sendRequest("PUT", "");
String payload = http.getString();

try with this code, if server .php, get data by $_REQUEST
