On my local machine I am using the latest version of Discourse. When I attempt to add a reply `within a topic`, I get the following error message:

The `post.get` error occurs in this bit of code:

I did a `console.log(post)` to see what it contained and the result was an object that has a post number of `(...)` . EDIT: Clicking on (…) yielded 1.

Additionally, when I try to add a `New Topic` (within the pipeline or in a topic), I get the error:

Would anyone know how to rectify this? Thanks!
