[Bug]: Nested too deeply - Weird behavior on Windows

[Mathissou01]

Environment

• Package: guava/filament-knowledge-base v2.0.0
• Installation: Fresh install (cache cleared and Filament assets published)

---

Issue I’m encountering the following error message:

The file "projet_folder.docs.knowledge-base.fr.01-getting-started" is nested too deeply. 
The maximum nesting depth is 3.

---

Current Directory Structure

/projet_folder
  /docs
    /knowledge-base
      /fr
        01-getting-started.md

KnowledgeBasePanelProvider:

->id('knowledge-base')
->path('knowledge-base')
->plugins([
    KnowledgeBasePlugin::make()
])

ConsultantPanelProvider:

KnowledgeBaseCompanionPlugin::make()
    ->knowledgeBasePanelId('knowledge-base')

Configuration (config/filament-kb.php):

return [
    'flatfile-model' => FlatfileNode::class,

    'cache' => [
        'prefix' => env('FILAMENT_KB_CACHE_PREFIX', 'filament_kb_'),
        'ttl' => env('FILAMENT_KB_CACHE_TTL', 'forever'),
    ],
];

---

Expected Behavior According to the [official documentation](https://github.com/GuavaCZ/filament-knowledge-base/blob/main/docs/v2/introduction.md), this structure should be valid.

---

Steps to Reproduce

1. Install the package via Composer on a fresh Filament setup.
2. Run php artisan cache:clear.
3. Run php artisan filament:assets.
4. Create the directory structure shown above.

---

Expected Result The documentation page should load correctly without nesting errors.

Actual Result An error is thrown indicating that the file is nested too deeply.

---

Question Why am I still getting this “maximum nesting depth” error, even though the structure seems to match the documented example?

---

Info The issue seems to appear only on Windows but not on MacOS.

Package Version

2.0.0

PHP Version

8.2.0

Laravel Version

11.9.0

Which operating systems does with happen with?

Windows

[Mathissou01]

@palmer-dev Found a solution that works on Windows. The issue didn’t occur on Linux or macOS.

->plugins([
    KnowledgeBasePlugin::make(base_path('docs' . DIRECTORY_SEPARATOR . 'knowledge-base')),
])

The problem was caused by the different directory separators used on Windows versus Linux/macOS. Using PHP’s built-in DIRECTORY_SEPARATOR constant ensures compatibility across all operating systems.
