Jenkins ver. 2.121.1
While developing/extending a Hubot plugin which uses the Jenkins remote api, I noticed the 'x-error' header on responses for telling users what went wrong. It isn't always returned, though. It would be really handy to remote API users to always have an x-error header available. I don't think this should be too hard since the API is already returning the error string inside the middle of a large chunk of HTML.
Here's an example:
POST 403 /job/skynet/job/the-job-name/config.xml
response headers:
