Without a configured
handler_id, thesession.handleralias is not created, and somes services depend on this alias specialy.Related to the reported issue above (affected version 4.4.9), the
ServiceHandlerInterfaceis an alias ofsession.handler, when execute :bin/console debug:container session.handler: The alias is not defined, so theContainerDebugCommandlook for a service containing thesession.handleras part of his name (ContainerDebugCommand::findServiceIdsContaining() is called and returns by defaultsession.handler.native_file)bin/console debug:container SessionHandlerInterface: The service is defined as an alias ofsession.handler, when callingContainerBuilder::getDefinition('session.handler')the exception occured as the alias is not defined.Implemented solution
Create a default
session.handlerwhen the paramhandler_idis not provided (I choosedsession.handler.native_filerather thanNullSessionHandler).Affected versions

3.4to5.1
