Greetings,

I've installed node-red-contrib-phantomjs and am having problems with the demo flow... seems handleData can not be found...

22 Sep 17:36:52 - [info] stderr:Console: ReferenceError: Can't find variable: handleData (from line # in "")

The resulting PNG is the right size, but it is black. Accessing /chart renders a chart.

One thing I do plan on changing is supporting URL to be passed in a msg...

Hum,

We use this module in a production bot but I didn't test it since a few month
I know that PhantomJS has issues with Fonts and Graphics on linux (there is requirement)
In the roadmap we also should replace PhantomJS by Chromeless (a new Webkit in Node)

any suggestions on what I can look for regarding the missing 'handleData' ? I don't see it referenced in any of the files.

Thanks.

It seems to work for me with the demo flow

The handleData() is defined in the D3 Bar Chart node it is called from phantomjs-script-snapshot.js but is not required.
