Question

Laravel

$this->validate($request, [
            'description' => 'required|min:20|max:3000',

Answer 1

You have an array and it is not a picture,
you need to check the array element

$this->validate($request, [
    'description' => 'required|min:20|max:3000',
    'images.*' => 'mimes:png',
]);
