Some of the query errors will crash the system

[rebelsky]

I've just been fixing a bug in module.exports.createAlbum in functions/albums.js. When the call fails, it calls res.end(error). But since the error was returned from an SQL query, there's no guarantee that it's a string. Since it's not a string, and res.end expects a string, the server crashes.

I've fixed the bug in albums.js, but a quick glance suggests that we call res.end(error) a lot.

aed7bb1 offers a temporary fix until we create a true error landing page.

We have a true error landing page. You can use utils.error to generate it. And making JSON is likely to have errors that are harder to reader, rather than easier.
