Bug with BelongsToMany repeator on edit

[sheepbild]

Hello,
I tried to use Repeator with BelongsToMany relationship. The classes are "Event (object in calendar)" -> "Reservation" <- "User (student)".
If I use the same code in a classical FilamentPHP Edit page, my "Repeator" function looks fine. When I click on "Save" I've this issue :

Call to a member function reservations() on null

Docs :
https://filamentphp.com/docs/3.x/forms/fields/repeater

My getFormSchema() function :

[
            View::make('forms.components.title-event'),
            DateTimePicker::make('start')
                ->label('Début')
                ->default(now())
                ->seconds(false)
                ->required(),
            DateTimePicker::make('end')
                ->label('Fin')
                ->default(now())
                ->seconds(false)
                ->required(),
            Repeater::make('reservations')
                ->relationship()
                ->schema([
                    Select::make('student_id')
                        ->label('Participant')
                        ->required()
                        ->relationship('student', 'name')
                        ->options(User::all()->sortBy('name')->pluck('name', 'id'))
                        ->searchable()
                        ->default(null),
                    Toggle::make('has_participated')
                        ->label('A participé'),
                    Toggle::make('is_paid')
                        ->label('Payé'),
                ])
                ->columns(1)

Make sure in your Custom Widget Class to include these 2 methods

protected function getFormModel(): Model|string|null
{
return $this->event ?? Reservation::class;
}

public function resolveEventRecord(array $data): Reservation
{
return Reservation::find($data['id']);
}

Thank you very much. I have been trying to debug this issue for whole afternoon. !
