I am trying to create a RESTlet that initiate a scheduled task, but getting INSUFFICIENT_PERMISSION, while I am an admin.

what role was used for the restlet's tokens?

Oh, you pointed me to the right direction. Fixed it. Thanks.

Scheduled and MapReduce scripts require some specific permissions in the role... I had issue with non-admin role and. submiting map-reduce task from restlet... Two persmissjons is expected : suite script and suite script schedule, but the last one Documents and folders are very strange
