Getting a 404 error when I click on "vote"

Hi, when I click on the "vote" button, I am getting a 404 error in which when I look at the URL, it is

localhost:4567/ideas//vote

I am doing something wrong in which it is not counting my vote and pending it to the url where ":slug" is.

Can someone help? Here is my Github repo:

I had the same problem and it had something to do with the line slug = slugify.slugify(title); (in the constructor of CourseIdea class). it was mistyped to slug = slugify.slugify(slug);

Make sure that the actual value passed to slug is not an empty string and is not null!
