Laravel Base table or view not found: 1146 Table

Im trying to get the 'diversities()' from items with a pivot table (belongToMany).

What am I missing?:

** Client works fine and Item and Client are identical (almost). The error I get is

Base table or view not found: 1146 Table 'restigo_spm.diversity_item' doesn't exist

and I dont have a diversity_item anywhere in the code, why is it searching for it?

Client:

{
   protected $fillable = ['name', 'diversity_id', 'type', 'enable'];

   public function diversities()
   {
       return $this->belongsToMany('App\Models\Diversity');
   }
}

ClientSchema:

        Schema::create('clients', function (Blueprint $table) {
            $table->id();
            $table->unsignedInteger('client_diversity_id')->nullable();
            $table->string('name')->unique();
            $table->enum('type', ['restaurant', 'coffee', 'bar']);
            $table->boolean('enable');
            $table->timestamps();
        });

ClientDiversity (pivot):

class ClientDiversity extends Model
{
    protected $table = 'client_diversity';
    protected $fillable = ['diversity_id', 'client_id'];

}

ClientDiversitySchema:

        Schema::create('client_diversity', function (Blueprint $table) {
            $table->id();
            $table->unsignedInteger('client_id')->nullable();
            $table->unsignedInteger('diversity_id')->nullable();
            $table->timestamps();
        });

Item:

class Item extends Model
{
    protected $fillable = ['name', 'diversity_id', 'catalog_number', 'price', 'has_vat', 'enable'];

    public function diversities()
    {
        return $this->belongsToMany('App\Models\Diversity');
    }
}

ItemSchema:

        Schema::create('items', function (Blueprint $table) {
            $table->id();
            $table->unsignedInteger('item_diversity_id')->nullable();
            $table->string('name');
            $table->string('catalog_number')->unique();
            $table->integer('price');
            $table->boolean('has_vat');
            $table->boolean('enable');
            $table->timestamps();
        });

Diversity:

class Diversity extends Model
{
    protected $fillable = ['name', 'item_id', 'client_id', 'enable'];

    public function clients()
    {
        return $this->belongsToMany('App\Models\Client');
    }

    public function items()
    {
        return $this->belongsToMany('App\Models\Item');
    }
}

DiversitySchmea:

        Schema::create('diversities', function (Blueprint $table) {
            $table->id();
            $table->string('name')->unique();
            $table->boolean('enable');
            $table->timestamps();
        });

Here is where I call it. The ClientControl code is exactly the same and works, but Item doesnt. ItemController:

class ItemController extends Controller
{
    public static function index()
    {
        $items = Item::with('diversities')->get();

        return new ItemCollection($items);
    }
