How to run this robot on the host?

Question

Hi I posted this question on php-telegram-bot/core/issues in Github but no one answered it!

This Telegram-bot doesn't work for me : longman/telegram-bot

1. I used composer require longman/telegram-bot for require project :

| vendor --------- >  | composer
| composer.json       | guzzlehttp
| composer.lock       | longman ---> telegram-bot ---> src
                      | psr
                      | ralouphie
                      | autoload.php

Do I have to upload all these files to my host ?!

2. I uploaded all the files and used the example-bot repository for set.php and hook.php and i uploaded these files in vendor/longman/telegram-bot/src.

3. In step 3, i created my robot in botfather.

4. Next, i edit set.php and hook.php for my robot and i used https://mysite/vendor/longman/telegram-bot/src/set.php for ser webhook!

By the way, these files are not capable of calling autoload.php file at all. So I changed the file path to the files:

- require_once __DIR__ . '/vendor/autoload.php';
+ require_once __DIR__ . '/../../../autoload.php';

This time I was able to set the webhook but every time i send a /start to the robot, I get this error on error_log and the robot does not work:

error_log and the robot does not work:
