Unexpected Syntax Error

[Amm3135]

Hi. I just use this SDK in Laravel, It's not working when I want to get simple information of bot
`<?php

use Illuminate\Support\Facades\Route;

Route::get('/', function () {

$response = Telegram\Bot\Laravel\Facades\Telegram::getMe();

$botId = $response->getId();
$firstName = $response->getFirstName();
$username = $response->getUsername();
dd($botId);

});
`
it is completely correct but i dont know what i am encounter with this error and it refers to call Facade Telegram:
Internal Server Error

JsonException
Syntax error

i have been really confused. can you help me with this problem?
