Cannot Save New Post: Uncaught TypeError: Cannot read property 'typeKey' of undefined

I went through this video (and last) to confirm I have everything correct, and it still does not work. I get this error in the console when trying to save:

Uncaught TypeError: Cannot read property 'typeKey' of undefined

It points to ember-data.js:10153. I am using beta 15 as instructed in the last video.

Also, if I use the latest version of ember data (1.13.0), I can save the post with no error, I see the post listed, but when I click on it, it's empty. When I click Edit, title and body are empty. The post title is there on the #/posts page, but disappears when I click edit.

I tried also using the b10 as Epicodus dude did in the video, but I get an even weirder error using that. Clearly there is something off with the Ember Data versions and the versions as instructed in the video.
