### **Analysis**

When rendering the view, menu items urls are generated. During this process, the parameter `:project_id` of the overviews/overviews route is constrained to match the regex `/(?!(new)$)(\w|-)+/` (defined in `modules/overviews/config/routes.rb`). As the identifier name is invalid, the regex does not match, the route is not found, and the view rendering fails.

A bug in friendly\_id gem is talking about the same issue: [to\_param does not work as expected when record fails to save and a new slug is set in memory norman/friendly\_id\#959](https://github.com/norman/friendly_id/issues/959).
