Personal Library - Undefined id in last 2 routes

Tell us what’s happening:

Hi everyone,

I’m having an issue with the Personal Library project and really can’t understand where it comes from.

Everything works fine except for the last 2 routes: app.route(‘/api/books/:id’).post and app.route(‘/api/books/:id’).delete.
If i console.log(, it returns undefined and crashes. Yet, if I use the app.route(‘/api/books/:id’).post route from the Test post to /api/books/{bookid} form above, it works perfectly (except that I still have to implement the commentcount increment).

I have no clue why id is returning undefined when using the Add Comment and Delete Book buttons from the Sample Front End form…

Any idea ?

Thanks a lot !

Damn, I spent hours looking for a solution and of course I found it minutes after opening this thread…

Issue was that in my get route, I was returning a book object with an id property, instead of _id, and changing this somehow solved the problem !
