Highcharts phantomjs export server can't parse json string

I can't get the highcharts export server to work when running phantomjs as a server.

I am able to get the Highcharts export server working when I use the first method they suggest:

phantomjs highcharts-convert.js -infile options1.json -outfile chart1.png -scale 2.5 -width 300 -constr Chart -callback callback.js

But when I try to use phantomjs as a server I always get:

Failed rendering: SyntaxError: Unable to parse JSON string

I have tried using the sample string Highcharts provided and the one found here

my post request looks like this:

curl -X POST -H "Content-Type: application/json" -d '{infile:{xAxis:{categories:["Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep‌​","Oct","Nov","Dec"]},series:[{data:[29.9,71.5,106.4,129.2,144,176,135.6,148.5,21‌​6.4,194.1,95.6,54.4]}]},constr:"Chart",outfile:"//tmp//chart.png"}' localhost:3003

You have to escape the double quotes. This works for me.

curl -H "Content-Type: application/json" -X POST -d '{"infile":"{xAxis: {categories: [\"Jan\", \"Feb\", \"Mar\"]},series: [{data: [29.9, 71.5, 106.4]}]}"}' 127.0.0.1:3005

Note: The 'outfile' parameter has no use here. Running phantomjs as a server, outputs always a image as a 64bit string representation.
