Argument 2 passed to Spatie\Searchable\SearchResult::__construct() must be of the type string, null given

Question

im using spatie/laravel-searchable for my website. it works very well in this function:

  public function index(Request $request)
  {
    $results = (new Search())
    ->registerModel(Product::class, 'name', 'price','barcode')
    ->registerModel(Category::class, 'name')
    ->registerModel(Catalog::class, 'name')
    ->registerModel(Color::class, 'fatitle','entitle')
    ->search($request->input('query'));
    return response()->json($results);
  }

but in some words(like:cu006), i have this error:

Argument 2 passed to Spatie\Searchable\SearchResult::__construct() must be of the type string, null given
vendor/spatie/laravel-searchable/src/SearchResult.php:19
public function __construct(Searchable $searchable, string $title, ?string $url = null)

In your model, when you create the getSearchResult function

 public function getSearchResult(): SearchResult
 {
     return new \Spatie\Searchable\SearchResult(
        $this,
        $this->title
     );
 }

If you write $this->title you need to make sure that your model actually contains the title field, if it doesn't it'll give you that error.

That saved me!! thanks alot. do you know if there is any way show other fields under title? like description to create a proper search result page – stoneshaq May 26 '20 at 23:46
@stoneshak there might be but I'm not sure, I wrote this answer when I came across the problem myself and started debugging, you'd need to try things out and see, or create another question – Alexandre Elshobokshy May 27 '20 at 07:51

public function getSearchResult(): SearchResult
{
    $companySlug = currentCompanySlug();

    $url = url('/'.$companySlug.'/'.config('global-search- url.'.class_basename($this)));
    $null = null;
    return new SearchResult($this, $this->field_name ?:$null, $url);
}

please add in your model.
