meteor-google-maps | Meteor package for the Google Maps Javascript API v3 | Map library

I'm using dburles:google-maps in my Meteor app. I have a collection called recorridos, where each document has a two arrays (ida and vuelta) of objects {lat: xxx, lng: yyy}. I'm retrieving one doc from the collection, and I'm creating two PolyLine's and setting them to the instance of the map, with a switch to alternate between ida and vuelta. It works fine, but sometimes, when I reload the page I get the following error:

I am working on google map application which uses the google map version3 api. I am using in particular the utility methods in google.maps.latLng, such as getbounds, computeDistanceBetween, contains, fromLatLngToPoint in order to compute whether the bound lies inside or not.

I am using package dburles/meteor-google-maps which allows me to compute some values at client side, but not at server side. I have to do some calculations on server, particularly at models. I wonder if there is a way use google map api on meteor server.

thanks in advance
