Laravel many to many Query

I have a many to many associations on Vendors and Orders models whenever I try to query the vendor Id I get

Argument 1 passed to Illuminate\Database\Query\Builder::cleanBindings() must be of the type array, int given

My code is

public function orders()
    {
        $vendor_id = Auth::guard('vendor')->user()->id;
        
        $orders = Order::whereHas('vendors', function($vendor) use($vendor_id){
            $vendor->whereIn('id', $vendor_id);
        })->orderBy('created_at', 'desc')->get();

       
        return $orders;
}

Please, how do I go about fixing this?
