Sort not working for type / status

[jmgasper]

In dev (api.topcoder-dev.com/v5/challenges), we are seeing empty results return for type and status sorting:

Example: https://api.topcoder-dev.com/v5/challenges?sortBy=type&sortOrder=desc&projectId=23080&page=1&perPage=10

Returning: []

We initially implemented the search here:

#528

We need to figure out what's going on, as this was working and is now going to be going to production shortly.
