medias can't be validated in settings section

[moathOSA]

i have a problem where my translated medias field can't be validated in the back-end

i tried all these roles 'medias[banner_image][en][0]' => 'required', 'medias[banner_image][en] => 'required', 'medias.banner_image.en.0' => 'required', 'medias.banner_image.en' => 'required', 'banner_image.en' => 'required',

nothing work for me

in the rules for update and in the rules for create the same

public function rulesForUpdate()
    {
        return $this->rulesForTranslatedFields([
            'medias[banner_image][en][0]' => 'required',
        ], []);
    }
