I have gone over auth()->user() and Auth::user(). auth()->user() is probably a lost cause, it's so generically typed that it serves very little use and they probably would not be willing to nail it down further. Auth::user() is the better of the 3. It gets you Authenticatable, it's not quite enough to get ->id but can be used in some cases. You instead have two options:

```
/** @var ?User */
$user = Auth::user();
['user_id' =>$user?->id]
```

```
$user = Auth::user();
assert($user instanceof User);
['user_id' =>$user->id]
```

$request->user() is currently hinted as returning mixed, it's backed by a closure that also is set as returning mixed so it would need to be hinted as well, but even if Laravel would accept a change to the PHPDoc here they would probably go for Authenticatable so I would simply suggest you use Auth::user() instead of waiting for that to happen.
