Error when using a model for og:image fallback

[Milos2504]

I use a model for og:image fallback. This works fine with pages which have a cover image. However if a page doesn't have a cover image, an error (also below) comes up when I try to access that page in the panel.

Model:

    public function metaDefaults(string $lang = null): array
	{

		return [

			// or any meta tag
			'og:image' => $this->cover() ? $this->cover()->url() : '',
			"og:image:width" => 1230,
			"og:image:height" => 600,

		];
	}

Error:

Fatal error: Allowed memory size of 536870912 bytes exhausted (tried to allocate 12288 bytes) in C:\xampp\htdocs\local\site\plugins\kirby-seo\classes\Meta.php on line 64

Removing the model makes the error go away.
