I am ambivalent about 200 for employee not found, but that is clearly a different category of error compared to an api version not existing. for employee not found, the error is purely in data: there is no responsive data, but the request itself was made to an existing endpoint/url/route correctly. no api version existing is an improperly made request: whether or not there is data cannot be determined as the request itself was problematic, so we never even got there.
