Error content not displayed

[Wikiki]

Hi,

I set this middleware at the top of the stack, The errors and exception are well intercepted (I saw them into my Logger) but my response content is not displayed.

I use the following code:
( new Middlewares\ErrorHandler( 'App::errorHandler' ) )->catchExceptions( true ),

And my handler is like

static public function errorHandler( ServerRequestInterface $request ) {
    //Get the error info using the "error" attribute
    $error = $request->getAttribute( 'error' );
    $response = ( new Response() )->withStatus( $error[ 'status_code' ] );

    switch ( $error['status_code'] ) {
      case 404:
        App::$view->setView( 'errorNotFound' );
        $output = App::$view->__invoke();
        $response->getBody()->write( $output );

      case 503:
        App::$view->setView( 'maintenance' );
        $output = App::$view->__invoke();
        $response->getBody()->write( $output );

      default:
        App::$logger->debug( $error[ 'exception' ]->getMessage() );
        App::$view->setView( 'errorServer' );
        $output = App::$view->__invoke();
        $response->getBody()->write( $output );
    }

    return $response;
  }

What am I doing wrong ?

Just for information I'm using middleman as dispatcher. And I'm facing the same issue using the dispatcher from Middlewares\Utils

Middleman is using an old version of the PSR-15 interface (0.2 instead the current 0.4). I recommend using the dispatcher from Middleware\Utils.
Anyway, I suspect this is a bug in your code:

• You should add a break after each case in the switch
• If you don't see the response, are you sure the body has content?
• Is being the response emitted?

Hi,

I used the dispatcher from Middleware\Utils but same result. I've already added a break after each case (not in the version I copied / pasted here sorry)
If I put a var_dump( $response->getBody() ); exit( 1); the page is well displayed.

Into my app I just do:
$dispatcher = new Middlewares\Utils\Dispatcher( $middlewares );
$response = App::$dispatcher->dispatch( ServerRequestFactory::fromGlobals() );

Do I have to do anything else to emit the response ? I thought the dispatcher handled that.

Nop, the dispatcher returns the response but does not output the content to the browser. If you're using diactoros, it provides some emitters, depending of your needs. For example:

$emitter = new Zend\Diactoros\Response\SapiEmitter();
$emitter->emit($response);

Thank you for all your job and for your answer.
