API does not seem to return error messages for non HTTP 200 responses

[lholman]

Taking a look at the API documentation we can see that we get a WebException and no Body text returned for the 304 (this is also the case for other errors including HTTP 405), this is confirmed using cURL.
Maybe this is linked to #69 too.
Our unit tests don't seem to be having such an issue.

So, I've identified the issue behind not getting the custom error body back from Additionator hosted on Azure (this is what the API dotnetfiddle code samples hit), it's an IIS setting, commit coming soon.
