Slim Error on redirecting from error callback

[X-Tender]

I have a strange issue. Thats the error callback of the JWT JwtAuthentication (1.x).

"error" => function ($options) use ($app) {
        return $app->redirect( $app->urlFor('index') );
    }

On my development system (mamp php 5.6) the rediect from the "error" callback works fine.
On my productions erver (1&1 php 5.6) I get the following error:

Type: Slim\Exception\Stop
File: /SERVERPATH/htdocs/app/vendor_modules/slim/slim/Slim/Slim.php

What could be wrong?!

Slim 2 uses exceptions internally for control flow. You are seeing one of these Slim 2 control flow exceptions. Look for differences in your development and production config.

Honestly thats not realy any difference except the DB Connect credentials.
So I sould better bother the slim developer about the issue :) ?!

It is Slim which throws the exception, not the middleware.

https://github.com/slimphp/Slim/blob/2.x/Slim/Slim.php#L1102-L1105
https://github.com/slimphp/Slim/blob/2.x/Slim/Slim.php#L1037-L1043
https://github.com/slimphp/Slim/blob/2.x/Slim/Slim.php#L1020-L1023

Why the Exception is ignored on development host and shown on live host I do not know. However quick Google search reveals this.

Thanks. I packed it now that way and it works :/ But it feels wrong.

try {
    return $app->redirect( $app->urlFor('index') );
} catch(\Exception $e) {}

Yeah I agree. I think that was the reason those Exceptions were dropped in 3.x.
