Cors error when return 413 status code

[jetien]

Hi,
when I try to upload file which exceed "request.body.max.size", I received the correct status code (in the Network panel on devTools window) but there is also an error on CORS (No 'Access-Control-Allow-Origin'...).

This error leads to the no statusCode and statusText on the javascript response.

Any ideas about this problem ?
