How can someone reproduce this issue?

[ferrassi]

just install DubugKit 2.2 in CakePHP v2.5.6

Ok. From the stacktrace something in your application is causing a closure to end up in the data DebugKit is trying to cache. Are you passing any closures into the view?

[markstory]

Closing as I don't know how to reproduce this and it has been a long time.

I faced same error.

in
PHP 5.6.30
CakePHP 2.8.3
DubugKit 2.2.4

When I tried to pass serializer from controller to .ctp with $this->set(), it raised same error.

my code:

$serializer = JMS\Serializer\SerializerBuilder::create()->build();
$this->set('serializer', $serializer);
