Meteor x Modulus Spiderable/PhantomJS


I am reading a ton of things on this issue but can’t figure out the answer.
I am on hosting our app on Modulus. I am using ongoworks:spiderable and dfischer:phantomjs and getting the following error.

spiderable: phantomjs failed: Error: Command failed: 
    at ChildProcess.exithandler (child_process.js:658:15)
    at ChildProcess.emit (events.js:98:17)
    at maybeClose (child_process.js:766:16)
    at Process.ChildProcess._handle.onexit (child_process.js:833:5) 

Since Google depreciated their AJAX crawling I really want to figure out how to fix this bug and move on.

Also, how do I test if my app is crawlable now since ?_escaped_fragment_= doesn’t do anything anymore.
