Is there anyway to use Promises in RESTlets, or are they not available?

Looks like you can use promises in server scripts if you're using SS2.1.

Test your script before you go very deeps with promises, I do remember an underlaying bug where promises do not inherit property the role permissions that start it…

I got the code to work, thanks for the help!

i'm curious what your use case is to want to use promises? I've found very few cases where promises would benefit my server-side code.

@Shawn Talbert Agree, promises are usually more commons or beneficial client side, where you normally do a pageInit promises to gather results that would be use later in sublistChanged and things like that. There are a couple of cases where promises server side are useful but to your point the percentages are low…

be very careful about your error handling with Promises, there is no global rejection handler

my advice would be to avoid promises here unless you have a legitimate advantage in using them.
