Submitting a job via REST fails to save SCM and polling settings

[imbacen]

I submitted a new job via GUI and then replicated the exact same JSON
with a REST call. The result is not the same unfortunately, the new job
is missing SCM and polling information but has slave label and build
command stored successfully.

I am calling Jenkins with basic authentication and www-urlencoded form
data with json in a field "json". I am guessing that scm and polling are
not being saved via json and I need to include the full form data aswell?

Best regards, cen

JSON recorded from GUI http request:

The 'hudson-triggers-SCMTrigger' and 'scm' properties are not being
saved by Jenkins.
