Security Trimmed Snippet and Script Editor Web Part

Hi all,

I need to security trim a list of sub sites retrieved via REST and jQuery. SharePoint's REST API is very inconsistent regarding security trimming, so I wanted to use a Security Trimmed Snippet. For a user with access to all sub sites it displays, but it gives me an "internal error" for a user who does not have access to 1 of the 10 sub sites that are outputted. Please help. This is what I have in the Script Editor Web Part currently. My goal is to have a security trimmed list of Sub sites.
