the question had answered solution doesn't work , don't know why : how log zend developer tools toolbar?

i open new question because can't comment , can't reply ask (it's avoid, right ?)

so, wanna add collector zenddevelopertools display variables. tried code , got error :

fatal error: uncaught exception 'zend\servicemanager\exception\servicenotfoundexception' message 'unable fetch or create instance modsession\configcollector.

and put in modsession/config/module.config.php

'invokables' => array(     'modsession\configcollector'           => 'modsession\collector\configcollector', ),  'view_manager' => array(     'template_map' => array(         'zend-developer-tools/toolbar/modsession-configs' => __dir__ . '/../view/zend-developer-tools/toolbar/modsession-configs.phtml',     ), ),  'zenddevelopertools' => array(     'profiler' => array(         'collectors' => array(             'modsession_configs' => 'modsession\configcollector',         ),     ),     'toolbar' => array(         'entries' => array(             'modsession_configs' => 'zend-developer-tools/toolbar/modsession-configs',         ),     ), ), 

i don't see wrong, names correct, doesn't find don't understand

thanks reply , explain me error

if indeed module.config.php you're missing service_manager key should wrapping array of invokables...

'service_manager' => array(     'invokables' => array(         'modsession\configcollector' => 'modsession\collector\configcollector',     ), ),
