Inaccessible site Symfony routing - forms

Question

Can anyone please help me I'm desperate here !!!
I am working on a symfony 3 project and I have different actions to persist data to database or to update it but none of them is working. The code is fine I'm guessing it's a problem with the routing. This one is the action to add element to database
public function newAction(Request $request)
{
...
if($request->isMethod('POST')) {
...
return $this->redirectToRoute('meeting_new', array(
'meeting' => $meeting
));
...
}
return $this->render('SocialProMeetingBundle::ajoutMeeting.html.twig', array('users'=>$users));
}
and this is the updating action
public function editAction(Request $request, Meeting $meeting)
{
...
if($request->isMethod('POST')) {
...
return $this->redirectToRoute('meeting_edit', array(
'id' => $meeting->getId()
));
}
return $this->render('meeting/edit.html.twig', array(
'meeting' => $meeting,
));
}
and this is my routing file
meeting_index:
path: /
defaults: { _controller: "SocialProMeetingBundle:Meeting:index" }
methods: GET
meeting_show:
path: /show
defaults: { _controller: "SocialProMeetingBundle:Meeting:show" }
methods: [GET, POST]
meeting_new:
path: /new
defaults: { _controller: "SocialProMeetingBundle:Meeting:new" }
methods: [GET, POST]
meeting_edit:
path: /{id}/edit
defaults: { _controller: "SocialProMeetingBundle:Meeting:edit" }
methods: [GET, POST]
meeting_delete:
path: /{id}/delete
defaults: { _controller: "SocialProMeetingBundle:Meeting:delete" }
methods: DELETE

One problem is in your function newAction where you are passing in a meeting parameter and the route doesn't handle it. This code:
return $this->redirectToRoute('meeting_new', array(
'meeting' => $meeting
));
Your route needs to handle the parameter like so:
meeting_new:
path: /new/{meeting}
defaults: { _controller: "SocialProMeetingBundle:Meeting:new" }
methods: [GET, POST]
