mshamaseen has created Issue #3512: GroupBy with count does not work in laravel-mongodb. This Jira ticket was filed by GromNaN

Issue Text:

• Laravel-mongodb Version: 5.7
• PHP Version: 8.4

Description:

`Message::where('broadcast_id', 3)>groupBy('status')>count();`

result to
<warning> WARNING </warning> Object of class Illuminate\Support\Collection could not be converted to int in vendor/laravel/framework/src/Illuminate/Database/Query/Builder.php on line 3932.

and the return value is always 1.

The reason for that is:
https://github.com/mongodb/laravel-mongodb/blob/7ae18756959ba9bc2b44c62d897d29bb1e39c5a2/src/Query/Builder.php#L610

It returns a collection if groupBy exists.

whereas Laravel count function on vendor/laravel/framework/src/Illuminate/Database/Query/Builder.php:3932 expects a number.
