Handling PostTooLargeException

Hi! I am trying to handle PostTooLargeException in my Laravel 5.5 application.

When I trying to upload too big file through my form I receive PostTooLargeException which I successfully catch in app\Exceptions\Handler.php, but on that step I would like to redirect user back to the page with form and show an error message.

I wrote following code:

class Handler extends ExceptionHandler
{
...
    public function render($request, Exception $exception)
    {
    ...
        if($exception instanceof PostTooLargeException){
                    return redirect()->back()->withErrors("Size of attached file should be less ".ini_get("upload_max_filesize")."B", 'addNote');
            }
    ...
    }
}

As a result I was redirected to the proper page but without any message and ErrorBag was empty. Did I something wrong with that redirection?

Thank you a help!

try to pass an array to withErrors()

->withErrors(["message" => "Size of attached file should be less ".ini_get("upload_max_filesize")."B"]);

Thank you for answer, but it also does not work, the ViewErrorBag is still empty

The ViewErrorBag is empty because session is not start in the Handler. Solution was previously described by @Talinon at https://laracasts.com/discuss/channels/laravel/exception-handler-for-posttoolargeexception

To make it works again I moved \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class from $middleware to $middlewareGroups array at the App/Http/Kernel.php
