I am using webwrite to make a post request. I can that the request is getting to the server and that the data is being sent. The server response with a 201 (Created) response. This appears to cause matlab to throw an error.

The call looks like

    webwrite('http://localhost:9999/register', registerData, weboptions('MediaType', 'application/json'));

registerData is a struct.

Is there a way to tell matlab that 201 is a successful/expected response? Do I need to make the server respond with 200 (Ok) instead, even though 201 is a more accurate response?

The error message and stack trace is

Error using readContentFromWebService (line 37)
The server returned the message: "Created" for URL,
'http://localhost:9999/registerdbstack' (with HTTP response code 201).
Error in webwrite (line 126)
[varargout{1:nargout}] = readContentFromWebService(connection, options);
 K>> dbstack
 > In matlab.internal.webservices.HTTPConnector/copyContentToByteArray (line 235)
   In readContentFromWebService (line 37)
   In webwrite (line 126)
   In myCode (line 83)

I am using Matlab 2015a (8.5.0.197613) on a 64-bit Mac.

Edit: add stack traces and version information

It appears that matlab has a bug in webwrite, where if the server returns a success code 2xx that is not 200, it is not possible to get the content returned by the web server.
