The issue I'm facing is that I need to test the structure of a response in which some properties are look-alike

Steps To Reproduce:

this is the response to test against :

]

this is can be returned from a route for easy testing.

$request = $this->get('/dummy-url-to-return-the-response');

$request
->assertJsonStructure(
[
            '*' => [
                'id',
                'product_id',
                'section_id',
                'image_id',
                'html_id',
                'index',
                'name',
                'description',
                'title',
                'backup',
                'required',
                'emailable',
                'type',
                'asset_id',
                'thumb_id',
                'image' => [
                    '*' => [
                        'id',
                        'product_id',
                        'image',
                        'thumb'
                    ]
                ],
                'html' => [
                    '*' => [
                        'id',
                        'product_id',
                        'image',
                        'thumb'
                    ]
                ]
            ]
        ]
)

If an object have an html object, the image object is null and vis versa.

Keep in mind that the structure was truncated for easier follow so assuming that I am writing this correctly, this is the message I keep getting.
