I am trying the one day tutorial of scout but whenever i try to launch the server and open the link it only opens once or twice then after that it keeps giving me initialization error on the page with this error message

Having a look at the method org.eclipse.scout.rt.client.clientnotification.ClientSessionRegistry.sessionStarted(ClientSessionRegistry.java:84):

  public void sessionStarted(final IClientSession session) {
    ensureUserIdAvailable(session);
    checkSession(session);

before checkSession is called (which throws the exception from your post) previously ensureUserIdAvailable(session); is called which basically just does a simple server call

BEANS.get(IPingService.class).ping("ensure shared context is loaded...");

to ensure initialization of the server session (which should also bring the userId to your client session).

Apparently this method does not set a userId on your client session; do you have any output on your backend server e.g. errors in the log?

On the server-side a userId should be assigned in org.eclipse.scout.rt.server.AbstractServerSession.start(String) which calls org.eclipse.scout.rt.server.AbstractServerSession.assignUserId(). Maybe no userId was assigned there? Do you have any log output here or maybe you could add a breakpoint there?
