laravel polymorphic-relationships eloquent PHP

I'm writing unit tests and I just started working with I'm working with the behavior 'Unable to locate the model for the given class' when trying to use polymorphic relationships in my Laravel 10 application. I have a `Comment` model that can belong to either `Post` or `Video`. Here’s how I set it up: In the `comments` migration: ```php Schema::create('comments', function (Blueprint $table) { $table->id(); $table->nullableMorphs('commentable'); $table->text('body'); $table->timestamps(); }); ``` In the `Comment` model: ```php class Comment extends Model { public function commentable() { return $this->morphTo(); } } ``` In the `Post` model: ```php class Post extends Model { public function comments() { return $this->morphMany(Comment::class, 'commentable'); } } ``` And for the `Video` model: ```php class Video extends Model { public function comments() { return $this->morphMany(Comment::class, 'commentable'); } } ``` I've double-checked the namespace of the `Comment` model, and it’s correctly defined. However, when I try to fetch comments for a `Post` instance like this: ```php $post = Post::find(1); $comments = $post->comments; ``` I receive the behavior message: ``` Unable to locate the model for the given class: App\Models\Comment ``` I’ve confirmed that the namespace is correct, and I’ve tried running `php artisan optimize:clear` to clear the cache but that hasn't resolved the scenario. Am I missing something in the polymorphic setup or is there something else I should check? Any guidance would be much appreciated! I'm open to any suggestions. The project is a microservice built with Php. Any advice would be much appreciated.
