Error in Laravel “Call to undefined method AppModelsBlog::getContent()”

I’m getting an error when rendering a model Blogs

My errors:

Call to undefined method AppModelsBlog::getContent()

Can you suggest what is the cause of the error.
Model code given below

<?php

namespace AppModels;

use IlluminateDatabaseEloquentFactoriesHasFactory;
use IlluminateDatabaseEloquentModel;
use AppModelsCategories;

class Blog extends Model
{
    public $table = "blogs";
    protected $fillable = [
        'id',
        'category_id',
        'title_ru',
        'title_ua',
        'slug',
        'img',
        'img_min',
        'url',
        'duration',
        'annotation_ru',
        'annotation_ua',
        'description_ru',
        'description_ua',
        'meta_ru',
        'meta_ua',
        'keywords_ru',
        'keywords_ua',
        'views',
        'type_record',
        'schedule',
        'published',
        'created_at',
        'updated_at'
    ];
    public function category()
    {
        return $this->belongsTo(Categories::class);
    }
    public function scopePublished($query)
    {
        return $query->where('published', true);
    }

}

This code helps to call the model Blog.
