Symfony >4 and accessing Details

[vchapple17]

We're upgrading to Symfony 4 and beyond and are having issues accessing the thruway.details in our controller that has the RPC's method.

We get the error the service 'thruway.details' is not defined.

1. Is this a service that needs to be public inside the ThruwayBundle?
2. Alternatively, is there a workaround to get the ArgsKw, session, and authId inside the RPC call?

 /**
     * @Register("ssd.rpc.lock", worker="realm1")
     */
    public function lockAction()
    {
        $details = $this->get('thruway.details');
        $session = $details->getDetails()->caller;
        $ids = $details->getArgsKw()->id;
        $options = json_decode(json_encode($details->getArgsKw()->options), true);
        $authid = $details->getDetails()->authid;
        ...
     }
