After changing the json path in build.js, the browser throws an exception

[somebodyZw]

I modified the JSON path in build.js to point to the JSON in my own project.F12 throws an exception:

Is it because my JSON format is not correct?I'm through http://2geojson.com/index.php, this web site to transform DXF converted to JSON, if is the format error, so I change how to convert JSON?

If we can transfer the project into server JSON (no matter what kind of server, C, C + +, JAVA, Python,. Net, etc.), HTML page parse the JSON data model, then it will be a very high commonality project, now I can't Node. Js and Python, if I want to finish a project (I am a JAVA developer), need based on your project to do?
