You need to update jenssegers/mongodb.
Looking at https://github.com/jenssegers/laravel-mongodb the compatability charts shows that 2.3 doesn't satisfy Laravel 5.3+.
The reason you're getting that specific error is because in Laravel 5.3 a change was made to the query builder so it would return a collection instead of an array, however, 2.3 of jenssegers/mongodb just returns an array. In version 3.1 of jenssegers/mongodb there is now a check to determine which version of Laravel you're using for this reason.
Hope this helps!
