Hi @maciejonek

What version of Flow are you using?
Run composer info neos/flow to get that info

Is this a issue that you see when you perform a specific action? And can you tell about your application, does it have any functionality that you think could cause this?

i dont know which flow version youre on (the line numbers seem to have changed)

but on flow-8.3-dev the $objectManager->setObjects is called here:

github.com

neos/flow-development-collection/blob/69832786775bc502563082adf0f5f0e035472332/Neos.Flow/Classes/Core/Booting/Scripts.php#L498


      
           * @return void
           */
          public static function initializeObjectManager(Bootstrap $bootstrap)
          {
              $configurationManager = $bootstrap->getEarlyInstance(ConfigurationManager::class);
              $objectConfigurationCache = $bootstrap->getEarlyInstance(CacheManager::class)->getCache('Flow_Object_Configuration');
          
          
    $objectManager = new ObjectManager($bootstrap->getContext());
          
          
    $objectManager->injectAllSettings($configurationManager->getConfiguration(ConfigurationManager::CONFIGURATION_TYPE_SETTINGS));
              $objectManager->setObjects($objectConfigurationCache->get('objects'));
          
          
    foreach ($bootstrap->getEarlyInstances() as $objectName => $instance) {
                  $objectManager->setInstance($objectName, $instance);
              }
          
          
    $objectManager->get(Dispatcher::class)->injectObjectManager($objectManager);
              Debugger::injectObjectManager($objectManager);
              $bootstrap->setEarlyInstance(ObjectManagerInterface::class, $objectManager);
          
          
    Bootstrap::$staticObjectManager = $objectManager;

and if null was passed, that indicates the flow cache is broken …

that should (obviously) not happen, but i think there might be something special in your system, as i never encountered this problem.
