Summary

I am trying to get chat_id in a custom command.

$chatID = $this->getMessage()->getChat()->getId();

But it returns null for chat_id all the time if language is set to Turkish.

I tracked issue and strtolower('getId') returns getId in Turkish instead of getid in Entity class.

mb_strtolower('getId') workings corrects and returns getid.

Current behaviour

It returns null chat_id.

Expected behaviour

It should return chat_id.
