Issues mapping the output of an IDCS call

Content

I created and IDCS connection today using OAuth and a client ID / secret. I then went into an integration I developed that intersects two roles and instead attempted to intersect a role with a group. The IDCS call that returns the members in a group (their emails) returns an array of objects. The objects have a property called "$ref":"..." Which returns fine but when I attempt to map the output it fails. I have a strong suspicion it is because of the dollar sign in the property name. Has anyone experienced this?
