Call to a member function hasTranslation() on null - Laravel

I am using Laravel Translatables. But when I execute I got an error like Call to a member function hasTranslation() on null. Here is my code.

<?php 
    if($slider->product->hasTranslation($locale))
    {
       $type = $slider->product->translate($locale)->product_name;
    }
    else{
       $type = $slider->product->translate('en')->product_name;
    } //echo $type; exit;

?>

$slider->product is not null and $locale has value 'en' This code is working fine yesterday, the only change I made is, from the admin panel I just removed the required validation from add product field.

Check the setup of your relation $slider->product is not null

and the model has use Translatable trait

there is a helper method called optional()

optional($slider->product)->hasTranslation($locale)

this method will avoid to throw an exception.

NOT RECOMMENDED TO USE IT (optional()) IF $slider->product MUST HAVE A VALUE

just shortcut for clean code

if(optional($slider->product)->hasTranslation($locale))
   $type = optional($slider->product)->translate($locale)->product_name;
else
   $type = optional($slider->product)->translate('en')->product_name;

I fixed this problem with another if condition. Modified code is

<?php if(!empty($slider->product)) {

        if($slider->product->hasTranslation($locale))
        {
          $type = $slider->product->translate($locale)->product_name;
        }
        else{
          $type = $slider->product->translate('en')->product_name;
        }
    }
?>
