One more thing
if you try to override the response from server side in your working app
*var graph =
{"nodes":[{name:"Peter",label:"Person",id:1},{name:"Michael",label:"Person",id:2},*
* {name:"Neo4j",label:"Database",id:3}],*
* "links":[{start:0, end:1, type:"KNOWS", since:2010},{start:0, end:2,
type:"FOUNDED"},*
* {start:1, end:2, type:"WORKS_ON"}]};*
you might get the same error. Is this something related to the format of
data ?
