Laravel 5.5 - Model guarded not working on PHP 7.3.22

[axdemelas]

• Laravel Version: 5.5.*
• PHP Version: 7.3.22
• Database Driver & Version: Oracle with "yajra/laravel-oci8": "5.5.*"

Description:

I have a project running on a production server with PHP 7.3.19. There are some models using protected attribute $guarded instead of $fillable. Everything is fine.

The problem started when I tried to move it to another server that has PHP 7.3.22. All models that has $guarded is not working with mass assignment method Model::create($attributes) because only created_at and updated_at values are being filled on database insert statement. Then I just switch these models to use $fillable and things started working normally.

What can be happening?

Steps To Reproduce:

1. Create a Laravel 5.5 project on an PHP 7.3.22 environment.
2. Implement a model with mass assignment $guarded attribute.
3. Connect to an Oracle database using yajra/laravel-oci8 driver.
4. Use Model::create($attributes) method.
