Public files don’t get served until dev server restarts for the first time about flow-router HOT 2 OPEN

I have the similar issue. But my app crash when i`m trying ti pass any FlowRouter params, like 'id'

FlowRouter.route('/editproduct/:id', {
name: 'editProduct',
action: function(params) {
BlazeLayout.render('pageContent', {wrapper: 'editProduct' });
}
});

without FlowRouter param '/:id' my public files loads correctly in template
Problem always comes up on the initial server start
Meteor -1.8; FlowRouter - 2.1

from flow-router.

Solved. In my case the error was in relative url of static files (css/bootstrap.min.css) loaded as (/editproduct/css/bootstrap.min.css) - that was wrong. Static files should be imported by absolute url like this:
<link href="/css/bootstrap.min.css" rel="stylesheet">
