middleware_stack.js:31 Uncaught Error: Handler with name 'route' already exists. Iron router Meteor

My code was working fine until last night and suddenly I am getting this error and routes are not working at all.

middleware_stack.js:31Uncaught Error: Handler with name 'route' already exists.

for simple routes like this:

Router.route('/admin/dashboard', {
   template:"adminDashboard"
});

Router.route('/admin/create/table', {
  template:"create_table"
});

I cannot figure out the error, I have checked all the routes. Have anyone else faced this error?
