Calling ->dump() on a field with sub_fields always returns error

[marcoluzi]

Description of the bug

Using ->dump() on a Field that has sub_fields always return the following error:

Fatal error: Uncaught Error: Call to a member function get() on array

The dump itself is returned but the error happens afterwards.

Dumps on other fields are returned without any errors. Also tested on the Repeater field with the same resulting error as above.

Steps to reproduce

register_extended_field_group([
	'title' => 'Kundeninformationen',
	'fields' => [
		Image::make('Logo'),
		Text::make('Firmenname'),
		Text::make('Strasse/Nr.'),
		Text::make('PLZ'),
		Text::make('Ort'),
		Text::make('Telefon'),
		Group::make('Social Media')
			->fields([
				URL::make('Facebook'),
				URL::make('Instagram'),
				URL::make('LinkedIn'),
				URL::make('X'),
				URL::make('YouTube'),
			])->dump(),
	],
	'location' => [Location::where('post_type', 'page')],
]);
