How to handle PHPStan issues with laravel-translatable?

[ziming]

When I run PHPStan on a codebase that uses laravel-translatable, i always get issues like these. How do I fix them?

Example line of code

            ->line('Loan Purpose: '.$this->user->referralSource->name) // name is a translatable field

PHPStan Issues

  220    Binary operation "." between 'Referral Source: ' and array results in an error.       

In HasTranslations.php trait, I see that translatable fields are given a cast of array

public function getCasts(): array
    {
        return array_merge(
            parent::getCasts(),
            array_fill_keys($this->getTranslatableAttributes(), 'array'),
        );
    }

Which PHPStan then mistook. I have many translatable fields so asking PHPStan to ignore each 1 of them doesn't seem practical too. So wonder if there are any suggestions on how to handle this.

Thank you!
