Title: Correct the lookup of keys for mapping POST.

Per [72598556](https://www.pivotaltracker.com/story/show/72598556). "Already mapped' was just the default error message for when the POST fails, which was traced to having an "undefined" key in place of the object/option type names, which was due to improper lookup, and is fixed below.
