laravel 5 UnexpectedValueException od odpowiedzi

Question

Używam laravel 5.1 iz jakiegoś powodu dostaję ten błąd od czasu do czasu:

UnexpectedValueException zgodnie Response.php 397: Zawartość odpowiedź musi być ciąg znaków lub obiekt implementujący __toString(), "boolean" podany.

To bardzo frustrujące, ponieważ jest to bardzo nieprzewidywalne i dzieje się tylko od czasu do czasu - więc bardzo trudno jest nawet debugować, ponieważ nie jest to zgodne. Mam prostą drogę po prostu zrzucić plik tłumaczenia, co następuje:

Route::get('test', function() { 
    return trans('restaurant'); 
}); 

Gdybym zachować odświeżania strony, pokazuje wyjście dobrze przez większość czasu. Jednak raz na 20-30 połączeń pojawia się błąd! Czy ktoś może rzucić trochę światła tutaj?

tutaj jest ślad stosu:

Answer 1

Wystarczy dodać obsługi wyjątku. Abyś mógł obsłużyć dane, które pojawią się, gdy wystąpi błąd.

Route::get('test', function() { 
     $response = trans('restaurant') 
     try{ 
      return $response; 
     } 
     catch(Exception $e) { 
      return []; 
     } 
    });
