my config.yml

    imports:     - { resource: parameters.yml }     - { resource: security.yml }     - { resource: services.yml }  # put parameters here don't need change on each machine app deployed # http://symfony.com/doc/current/best_practices/configuration.html#application-related-configuration parameters:     locale: en  framework:     serializer:         enabled: true     #esi:             ~     #translator:      { fallbacks: ["%locale%"] }     secret:          "%secret%"     router:         resource: "%kernel.root_dir%/config/routing.yml"         strict_requirements: ~     form:            ~     csrf_protection: ~     validation:      { enable_annotations: true }     #serializer:      { enable_annotations: true }     templating:         engines: ['twig']         #assets_version: someversionscheme     default_locale:  "%locale%"     trusted_hosts:   ~     trusted_proxies: ~     session:         # handler_id set null use default session handler php.ini         handler_id:  ~     fragments:       ~     http_method_override: true  # twig configuration twig:     debug:            "%kernel.debug%"     strict_variables: "%kernel.debug%"  # doctrine configuration doctrine:     dbal:         driver:   pdo_mysql         host:     "%database_host%"         port:     "%database_port%"         dbname:   "%database_name%"         user:     "%database_user%"         password: "%database_password%"         charset:  utf8         # if using pdo_sqlite database driver:         #   1. add path in parameters.yml         #     e.g. database_path: "%kernel.root_dir%/data/data.db3"         #   2. uncomment database_path in parameters.yml.dist         #   3. uncomment next line:         #     path:     "%database_path%"      orm:         auto_generate_proxy_classes: "%kernel.debug%"         naming_strategy: doctrine.orm.naming_strategy.underscore         auto_mapping: true  # swiftmailer configuration swiftmailer:     transport: "%mailer_transport%"     host:      "%mailer_host%"     username:  "%mailer_user%"     password:  "%mailer_password%"     spool:     { type: memory }  gregwar_captcha: ~ fos_rest:     routing_loader:             default_format: json     view:             formats:                 json: true                 rss: false # removing them work                 xml: false 

and here controller:

<?php  namespace appbundle\controller;  use fos\restbundle\controller\fosrestcontroller; use symfony\component\httpfoundation\request; use fos\restbundle\view\view; use appbundle\response afspraakresponse;  class afsprakencontroller extends fosrestcontroller {      public function postafspraken(request $request)     {          $data =  $this->getafspraken();         $view = $this->view($data, 200)             ->settemplate("mybundle:users:getusers.html.twig")             ->settemplatevar('users')         ;          return $this->handleview($view);     }      public function redirectaction()     {         $view = $this->redirectview($this->generateurl('getafspraken'), 301);          return $this->handleview($view);     }      public function getafspraken() {          $repository = $this->getdoctrine()             ->getrepository('appbundle:uren');          $result = $repository->findall();         return $result;      } } 

when run localhost:8000/test whole page of errors honnest first line says this:

{"error":{"code":500,"message":"internal server error","exception":[{"message":"unable parse controller name \"appbundle:controller:afsprakencontroller:postafspraken\".","class":"logicexception"
