Attempt to read property "component" on null

[cardi777]

I am setting up a repeater using hasMany(). It is a basic system of assigning videos to categories.

I don't think this is a bug, I think it's something I don't understand.

It saves my repeater data when adding videos to categories, but when i go to edit a category with videos assigned, I get an error (see at bottom)

Category model:

    public function videos()
    {
        return $this->hasMany(Video::class)->orderBy('position');
    }

Category repository, which is where i thought the error is probably caused?:

    public function afterSave($object, $fields)
    {
        $this->updateRepeater($object, $fields, 'videos', 'Video', 'Video');
        parent::afterSave($object, $fields);
    }

    public function getFormFields($object)
    {
        $fields = parent::getFormFields($object);
        $fields = $this->getFormFieldsForRepeater($object, $fields, 'videos', 'Video', 'Video');
        return $fields;
    }

form.blade.php:

@extends('twill::layouts.form')

@section('contentFields')

    @formField('input', [
        'name' => 'description',
        'label' => 'Description',
        'maxlength' => 100
    ])

    @formField('repeater', [
        'type' => 'video',
        'name' => 'Video',
        'max' => 999,
        'buttonAsLink' => false,
        'reorder' => true
    ])

@stop

repeaters/video.blade.php file:

@twillRepeaterTitle('Videos')
@twillRepeaterTrigger('Add video')
@twillRepeaterGroup('app')

@formField('input', [
'name' => 'title',
'label' => 'Title',
'required' => true,
])

error data is shown in screenshot
