Update Method not working, no access to variables

Hi,

sorry for such a stupid question but I can't find the root cause. Maybe you can give me a hint.

I have created a laravel app for a bus reservation with normal CRUDs. I think the issue is related to route model binding of $booking is not working correctly, not getting the Object details for id 116 .... but more details below. If you need more, please ask.

Here the web.php

// Busbookings
Route::delete('busbookings/massdestroy', 'BusBookingController@massDestroy')->name('busbookings.massDestroy');
Route::delete('busbookings/destroy', 'BusBookingController@massDestroy')->name('busbookings.destroy');
Route::get('busbookings', 'BusBookingController@index')->name('busbookings.index');
Route::get('busbookings/{booking}', 'BusBookingController@show')->name('busbookings.show');
Route::get('busbookings/{booking}/edit', 'BusBookingController@edit')->name('busbookings.edit');
Route::put('busbookings', [BusBookingController::class, 'update'])->name('busbookings.update');

Blade views of index and show are working as expected. But when I press OK in edit.blade.php access to the parameters is not working.

edit.blade.php

@extends('layouts.admin')
@section('content')

<div class="card">
    <div class="card-header">
        {{ trans('global.edit') }} {{ trans('cruds.busbooking.title_singular') }}
    </div>

    <div class="card-body">
        <form method="POST" action="{{ route("admin.busbookings.update", [$booking->id]) }}" enctype="multipart/form-data">
            @method('PUT')
            @csrf
[...]
<div class="form-group">
                <button class="btn btn-danger" type="submit">
                    {{ trans('global.save') }}
                </button>
            </div>
        </form>
    </div>
</div>

@endsection

BusController.php

 public function update(UpdateBusBookingRequest $request, BusBooking $booking)
    {
        //dd($request);
        //dd($booking);
        //dd($request->query() );
        
        $booking->update($request->all());

        return redirect()->route('admin.busbookings.index')->with('success','Buchung erfolgreich verarbeitet.');;
    }

Debug from dd($request)

Debug output from $request->query(); looks like this

array:1 [▼
  116 => null
]

I think this is the issue ...

  +query: Symfony\Component\HttpFoundation\InputBag {#2047 ▼
    #parameters: array:1 [▼
      116 => null

Why is it not working with the object binding to busbooking?
