TypeError when trying to declare a call to server.GetPlayersInSegment();

When trying to save an update to our Cloud Script, I receive this error regarding the new "server.GetPlayersInSegment();" call. I'm unsure if there is something I should be doing differently when calling this function.

Again, this is not during runtime, this is just when trying to save the cloud script update.

The Error:

TypeError: Cannot read property 'server_request' of undefined at server.GetPlayersInSegment (Script Document:535:76) -> server.GetPlayersInSegment = function(request) { return __playfab_internal.server_request('/Server/GetPlayersInSegment', request); }

The call:

var allPlayersSegmentResult = server.GetPlayersInSegment({ "SegmentId" : ALL_PLAYERS_SEGMENT_ID,
                                                            "MaxBatchSize" : 2000,
                                                           "SecondsToLive" : 30 });

Thanks,
