How to validate the pro image field in backpack for laravel?

I have the mutator as the example in https://backpackforlaravel.com/docs/5.x/crud-fields#image-pro

But I had trouble including the validation rules.

I tried with 'photo' => 'nullable|base64image|base64mimes:jpg|base64max:2048',

And it works when I upload a new image, but if I have an image and try to edit another field it flags the errors:

"The photo field must be an image."

"The photo field must be a file of type: jpg."

Does anyone have any idea why this is happening? or what is the correct way to validate with the pro image field?

    namespace AppHttpRequests;

use IlluminateFoundationHttpFormRequest;

class YourFormRequest extends FormRequest
{
    public function rules()
    {
        return [
            'pro_image' => 'image|mimes:jpeg,png,jpg,gif|max:2048', // Adjust the allowed file types and maximum file size as per your requirements
        ];
    }
}

    namespace AppHttpControllers;

    use AppHttpRequestsYourFormRequest;
    use IlluminateHttpRequest;

    class YourController extends Controller
    {
    public function store(YourFormRequest $request)
    {
    // The request is valid, proceed with storing the data or handling the file
    // The uploaded file is available via $request->file(‘pro_image’)

        // Example: Storing the uploaded file
    $proImage = $request->file('pro_image');
    $proImage->store('your-directory'); // Adjust the storage path as per your requirements

    // Additional processing or database storage can be done here

    // Redirect or return a response
}

    i do this validation with custom validator extend, like this:

    app/Providers/AppServiceProvider.php

    <?php

namespace AppProviders;

use IlluminateSupportServiceProvider;
use IlluminateSupportFacadesValidator;

class AppServiceProvider extends ServiceProvider
{
    /**
     * Register any application services.
     */
    public function register(): void
    {
        //
    }

    /**
     * Bootstrap any application services.
     */
    public function boot(): void
    {
        Validator::extend('base64image',function($attribute, $value, $params, $validator) {
            $explode = explode(',', $value);
            $allow = ['png', 'jpg', 'svg'];
            $format = str_replace(
                [
                    'data:image/',
                    ';',
                    'base64',
                ],
                [
                    '', '', '',
                ],
                $explode[0]
            );

            // check file format
            if (!in_array($format, $allow)) {
                return false;
            }

            // check base64 format
            if (!preg_match('%^[a-zA-Z0-9/+]*={0,2}$%', $explode[1])) {
                return false;
            }

            return true;
        });
    }
}

    app/Http/Requests/XYZRequest.php

    'photos' => 'required|base64image',

    Is working always.

    Cheers
