The expression return $locale also could return the type array which is incompatible with the documented return type string.

The method runningInConsole() does not exist on Illuminate\Container\Container. Are you sure you never get this type here, but always one of the subclasses?

It seems like request()->server() can also be of type string; however, parameter $array of Illuminate\Support\Arr::has() does only seem to accept ArrayAccess|array, maybe add an additional type check?
